USA:
Curry, Harden, Durant, James, Howard
Paul, Westbrook, Thompson, Anthony, Aldridge, Cousins, Davis
World:
Parker, Irving, Nowitzki, P. Gasol, M. Gasol
Dragic, Wiggins, Ginobli, Diaw, Batum, Ibaka, Horford
I think I have the nationalities right, but I'm not sure. The guards were really hard for the World team, so I just put Wiggins/Greek Freak. I'm sure I'm missing somebody.
EDIT: Fixed the guards; I didn't know Irving was an Aussie.
