AA in live 2/5 NL game

Playing in 9-handed live 2/5 NL game.

Thhis hand came up and I want to hear about how I played it. Feel free to flame. Table image is TAG, but lucky. I previously made a couple of hands on the river in small pots and got my big river bets paid off. I am big stack at the table by about only the villian is anywhere near me. Read on villian is that he is a little loose pre-flop, but solid after that. Villian wins most hands by betting aggressively. He has shown down relatively few. Some of the hands that he has shown have been hands that he never should have called the pre-flop bet with. Here's the hand

UTG+1 (villian) limps (~$1,300)
MP1 limps ((~$250)
MP2 limps (~$200)
MP3 raise to $68 (all-in)
Button (Hero) calls with A [img]/images/graemlins/heart.gif[/img]A [img]/images/graemlins/club.gif[/img] (~$1,700)

Folds to villian who calls. All others fold.

3 take the flop, one all-in.

Flop: J,7,2 rainbow.

Villian: Check.
Hero: Bet $75.
Villian: Raise to $250.
Hero: Raise to $1,000.
Villian: All-in for ~$300 more.
Hero: Call.

Please comment on my play. I will give results later.

Thanks,
Vince
