Stars $22 Deepstack -- early play with top two?

[Insane_Steve]

I'm trying to learn early strategy in MTTs a bit better. I find that I tend to have an average or below average stack a lot late and thus need to find better spots to win chips early.

Reads: UTG+1 is a complete moron. No reads on MP2, but based on the pre-flop min-reraise, MP2 is also a complete moron.

Pre-flop: (9 players) Hero is UTG with Q[img]/images/graemlins/club.gif[/img] A[img]/images/graemlins/club.gif[/img]
<font color="#cc0000">Hero raises to t70</font>, UTG+1 calls t70 <font color="aaaaaa">(pot was t100)</font>, MP1 folds, <font color="#cc0000">MP2 raises to t120</font>, 2 folds, Button calls t120 <font color="aaaaaa">(pot was t290)</font>, SB calls t110 <font color="aaaaaa">(pot was t410)</font>, BB folds, Hero calls t50 <font color="aaaaaa">(pot was t520)</font>, UTG+1 calls t50 <font color="aaaaaa">(pot was t570)</font>.

Flop: 8[img]/images/graemlins/diamond.gif[/img] A[img]/images/graemlins/spade.gif[/img] Q[img]/images/graemlins/heart.gif[/img] (t620, 5 players)
SB checks, <font color="#cc0000">Hero bets t450</font>, UTG+1 calls t450 <font color="aaaaaa">(pot was t1070)</font>, <font color="#cc0000">MP2 raises to t900</font>, 2 folds, <font color="#0000cc">Hero ????</font>

How's my line, both pre-flop and after the flop? What's the line after the expert min-raise by MP2?
