We just need three tools to get the job done:

Nexus Mod Manager

This is the most popular tool to get all your mods organized and up-to-date.

LOOT

Installing mods on Bethesda games can be a pain in the ass, especially if you try to install a lot of possibly-colliding mods. This tool keeps the load order straight.

FO3Edit

Fallout 3 itself comes out-of-the-box with certain errors in the main and DLC files, and this tool comes in handy to correct them. Besides, this is THE tool to create a merged patch to run the game with an absurd amount of mods.
