Re-evaluating my play... a couple hands

[skoal2k4]

I've been playing like [censored] lately and have started questioning the way I play certain situations.

Hand 1:
PokerStars No-Limit Hold'em Tourney, Big Blind is t20 (9 handed) FTR converter on zerodivide.cx

Hero (t1500)
UTG (t1220)
UTG+1 (t2030)
MP1 (t1030)
MP2 (t1450)
MP3 (t1160)
CO (t1920)
Button (t1590)
SB (t1480)

Preflop: Hero is BB with Q[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/diamond.gif[/img].
UTG calls t20, UTG+1 calls t20, <font color="#666666">1 fold</font>, MP2 calls t20, <font color="#666666">1 fold</font>, CO calls t20, Button calls t20, <font color="#666666">1 fold</font>, Hero ???
