Top set QQ deep stacked early in Stars 18k guaranteed

Just moved to this table as I get QQ UTG. 3bet will often be AA/KK/AK here I'd say?

PokerStars No-Limit Hold'em Tourney, Big Blind is t30 (9 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

CO (t5630)
Button (t2075)
SB (t3530)
BB (t2815)
Hero (t7430)
UTG+1 (t3480)
MP1 (t1985)
MP2 (t4430)
MP3 (t1630)

Preflop: Hero is UTG with Q[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/spade.gif[/img].
<font color="#CC3333">Hero raises to t90</font>, <font color="#666666">4 folds</font>, <font color="#CC3333">CO raises to t330</font>, <font color="#666666">3 folds</font>, Hero calls t240.

Flop: (t705) 9[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/diamond.gif[/img], 5[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets t240</font>, <font color="#CC3333">CO raises to t900</font>, <font color="#CC3333">Hero ?

What do I do here and why? And is my small bet into pf 3better good?
