you have to download netbattle from their forum... there's a thread about online battling floating around somewhere made by demonchaos (not the one by mana lugia as that one is... out of date.. lol)... go to that.
Nah... when you're using the team builder, one of the options up top is the pokedex or movedex... I usually use the movedex to help me memorize stats, and the pokedex to look for moves and so on. If you want another Pokedex, go to Meowth346's at pokemon forever. However, you can't use that pokedex if you're using internet explorer (or at least, it shows up darn ugly) due to Meowth346's anti-MS nature.
I'm sorry if I only give legal movesets though, but that's what the majority wants anyway
