Decided on creating a topic for the best sources of information on the net that I thought of, so people wouldn't ask for all that fluffy stuff.
Pokmon Forever - Includes all sorts of information on movesets, has a PokDex with advanced entries, and information on most aspects of the game, plus dialogue translations for certain new features in the games. The PokDex has language selections, too!
Aspects of interest:

Serebii.net - One of the biggest Pokmon Fansites on games, TV shows among other things, but gives stuff like suggested movesets and the like.
That's all I got, lol.
