AA Postflop help

[TurtlePiss]

What's your play in this situation?

Should I just shove all in on the flop if I know I'm going to have to call an all in raise (4:1), or bet less, or was my play correct? Perhaps raise more preflop? Any help is appreciated.

Reads: Villain is 32/26/6.2 over 141 hands. Besides that, I've seen him show down rather crappy cards with rather horrible play.
