What goodies should I get for 2k11

Hi everybody. Just picked up NBA 2k11 for practically nothing as my first PS3 bball game ever. Obviously the rosters are a bit dated but it looks amazing! Can anyone recommend some downloads I should try out to enhance the game? I just saw a roster I'm going to try, but what about draft classes? are there things other than that out there I should get?

Sorry for such a basic question, but I'm really not sure what my "starter kit" should consist of.

There may be some roster downloads you can get here or on OS, but the other mods and such are only for the PC version of the game.

OK thanks for explaining.
