The  mod adds a hell of a lot of stuff so I’ll let you browse through the original mod thread at the Minecraft Forums to see the complete feature list.

To install this mod you’ll need to make sure you install the following dependencies (the links below are for the 1.0 compatible versions of each mod – to see the updated mod information click the “lastest” link next to those that have one):

• Modloader by Risugami (latest)
• ModloaderMP by SDK, updated by Flan
• AudioMod by Risugami
• PlayerAPI by Flan, updated by Divisor (latest)
• ShockAhPI by Shockah

The author was kind enough to post a great guide for installing the mod:

Once you have installed the above mods, you can install the Aether:

1. First of all, go to your start menu. If you have Windows 7 there should already be a search bar there. If you use Windows XP, find a program on the side called “Run” and open it. Once you’ve clicked on the search bar, type in %appdata%
2. This should open up a folder called Roaming with a bunch folders inside. On the very top should be a folder called “.minecraft”. Open it. Once inside, open another folder called “bin”, and then open the “minecraft.jar” file with Winrar.
3. Now, go back to the “Aether_1.04″ folder then “Jars” folder that you downloaded before. Inside there should be a bunch of folders and files. Drag them into the “minecraft.jar” you opened up recently with Winrar and press yes if it asks you to replace some files. Once done, delete the folder inside called “META-INF”.
4. After that, you must go back to the original “.minecraft” folder that you were in before the “bin” folder. Once you are inside that folder, go back to the “Aether_1.04″ folder and drag both the “resources” folder into “.minecraft”. Press yes if it asks you to merge any folders.
5. Close down all the windows and start up Minecraft. Wait a while, and if it ends up black screening then you have a problem. If not, then enjoy!

If you happen to use Too Many Items (commonly known as TMI), it must be noted that you must install it AFTER you’ve installed the Aether, otherwise it will not work correctly.

This is a pack which includes (actually) 3 managers: The Config Manager, The Update Manager and the Language Manager.
For Players:
For players it’s just a mod which has to be installed if it’s required. Download for the pack is below.
For Modders:
The config manager gives you the abillity to do the basic thing and make a config for your mods and you can get a free block or item ID. Also modders can make different config files for one mod and also specify a path to their config(s).
The Update Manager let users know when updates for your mods are available. If it’s so, the player gets a chat message when entering a world once, each minecraft session. On servers, it will write into the server log if there’s an update available.
The Language Manager can handle multiple language files for one mod. That means, if your mod is initially written in english, you can use the Language Manager and let it search for language files in the specified path. If it find one, it loads the localizations in there and add them to the equivalent language in Minecraft. Language files must have the language code as file name, for example a language file written in spanish must be named “es_ES.txt”. The file extension can be either txt, lang or SAPLang.

This mod is required for some of the mods on ModMinecraft – only download and install this if the mod you want to use requires it.

Here’s how it works: A clay soldier is an item you can hold in your hand. It is crafted using a clay block (for substance) and soulsand (for sustaining intelligent life). Specifically, one block of clay and one block of soulsand can be used to create four soldiers. Once you have a nice little pile in your hands (up to 16), right-click to place them all at once. They will quickly spread out and begin to roam the landscape. They walk slow and don’t jump very high, but they have enough arm strength to climb up a single block. Unfortunately, since they lack a decent skeletal support structure (or even skin, for that matter), their delicate figures can be horribly mutilated by even the weakest of blows. A player can cripple a clay soldier in just a single punch. So naturally, they aren’t hostile towards anything bigger than themselves. So, what in the world are they qualified to fight against? …Other clay soldiers, of course!

This mod requires Manager Pack mod and Forge API.

Create and enchant items in-game, including mod items. Save and load entire inventories. Create unlimited stacks and tools. Switch game modes, test mods, create huge survival worlds, and more. Updated quickly!

Install: Read the Installing Mods page on the Minecraft Wiki. Search for Install TooManyItems on YouTube. The community has made lots of video tutorials. Thanks guys!

Turn On/Off: Press the “o” key while in the inventory screen. You can change this key by editing the configuration file.

Add items: Left-click on items in the right sidebar to add full stacks, or right-click to add one at a time.

Configuration file: Find the directory in which your minecraft saves folder and options.txt are, and once you have used TMI at least once you will also find TooManyItems.txt there. This contains options that you can change, not all of which are documented yet.

Spawners: In some previous versions, to create different kinds of spawners, edit the “spawner” line in the configuration file. Use at your own risk; in some (older) versions of Minecraft, spawners of non-mob entities such as boats can crash the game and wreck your save.

Unlimited stacks/tools (single-player only): Shift-left-click on items in the right sidebar to add unlimited stacks OR unlimited-use tools or flint and steel. ModLoader is required for “true” unlimited stacks. Without ModLoader the quantity of >64 stacks will refresh when you open your inventory.

Tabs: Use the chest, star, and book icons to change between the item, favorites, and enchant tabs.

Favorites: This allows you to save commonly used items. ADD to the favorites panel by: (1) clicking an item on the favorites panel, (2) alt-clicking an item in the items panel, or (3) clicking the Favorite button in the enchant panel. REMOVE an item from the favorites panel by alt-clicking it.

Enchanting: (in SP, or may work on some Bukkit servers) Click an item on the enchanting panel to switch to that type of item. Use the + and – buttons to change the levels of individual enchantments. Click the Create button to make the enchanted item once, or the Favorite button to add it to the favorites panel.

Trash (single-player only): Drop an item stack on the item sidebar or the trash icon to delete it. Click the trash icon to turn “delete mode” on and off (in “delete mode” you will delete any item you click on — useful for selectively deleting a lot of items). Shift-click thee trash icon to wipe out your inventory.

Game mode: Click the “S”, “C”, and “A” icons on the toolbar for survival, creative, and adventure mode, respectively.

Time: Click the sun and moon icons to set the time to sunrise, noon, sunset, or midnight.

Difficulty: Click the creeper icon to toggle the difficulty without having to go into game preferences.

Health/hunger: Click the heart icon to set health and hunger to max.

Save states (single-player only): Several slots are available for you to save your entire inventory and restore it later. (The “x” button next to a saved state will remove it.) This can be used to save your “real” inventory before editing, save a blank inventory to clear out everything you’re holding, save a full inventory of materials, share inventories between characters, etc.

Multiplayer: You need to be a server op. Also, every non-vanilla server works a little differently. The command issued to the server to give you items is configured in TooManyItems.txt as “give-command”. In this command, you should put {0} for the player’s username, {1} for the item ID, {2} for the quantity, and {3} for the damage value. If {3} isn’t in the command, items with damage values other than 0 won’t show up.

Vanilla server command: /give {0} {1} {2} {3}

* Since the vanilla server used to not support item damage with the give command, TMI may still have /give {0} {1} {2} by default. You can now add {3} to the end. The default will be updated in a future TMI version.

Bukkit with the Essentials mod command: /item {1}:{3} {2}

Fast crafting: Right-click on the output square when crafting to craft the maximum possible amount. (Works while the inventory overlay is disabled).

This mod requires a HD textures mod – I recommend OptiFine.

Unfortunately at the time of posting this (21/01/2012) the mod hasn’t been updated for the latest version of Minecraft but here’s hoping the developer hasn’t abandoned it for good!

You can check out the BossCraft thread on the Minecraft Forums to watch for an update and to read more details about what the mod can do.
