I had the demo on the 360 before I bought the game.
I don't know wheter the controls on the 360 are the same, but I could do everything you mentioned.
The only thing that was cut in the demo was calling plays and do coaching stuff via the D-Pad.
The right analog stick is the shot stick (PS3 controls?) which I first thought is dumb, but I now i can't live without it.
Doing a pump-fake is like in NBA Live. Either press the shot button shortly or just nudge the shot stick.
You can back down with L2.
You can do crossovers with the new Isomotion. You can try it with holding RT (R2 on Ps3) and just jiggle the left analog stick.
That
video explains the Isomotion better, though.
