Second guessing... how horrible was this?

Ultimate Bet No-Limit Hold'em Tourney, Big Blind is t30 (10 handed) converter

BB (t1790)
UTG (t1125)
UTG+1 (t1335)
UTG+2 (t1605)
MP1 (t980)
MP2 (t1650)
Hero (t1550)
CO (t1815)
Button (t1375)
SB (t1775)

Preflop: Hero is MP3 with A[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/heart.gif[/img].
UTG calls t30, <font color="#666666">3 folds</font>, MP2 calls t30, <font color="#CC3333">Hero raises to t110</font>, <font color="#666666">4 folds</font>, UTG calls t80, MP2 folds.

Flop: (t295) J[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/diamond.gif[/img], 6[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">UTG bets t295</font>, Hero calls t295.

I wasn't disappointed in the flop here at all. Question is, do I assume this guy is only betting to discourage a flush draw from continuing? Should I have raised? Pushed?

Turn: (t885) 4[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">UTG bets t720 (All-In)</font>, Hero folds.

Was this a mistake? Should I have called assuming his bet on the flop meant he wasn't on a flush draw?

Final Pot: t1605

Wow.

Push/re-raise the flop and it isn't even close.

That's what I was afraid of.
