Post-flop: Dealing with 3-flush turns

[otctrader]

Villain doubled up on a set, otherwise nothing out of the ordinary from the parties invovled. It's a Stars $27 turbo, play is of Party 22/33 caliber w/deep stacks.

PokerStars No-Limit Hold'em Tourney, Big Blind is t50 (7 handed) converter

SB (t1595)
BB (t870)
Hero (t1365)
MP1 (t3335)
MP2 (t1540)
CO (t3305)
Button (t1490)

Preflop: Hero is UTG with A[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/spade.gif[/img].
Hero calls t50, <font color="#666666">1 fold</font>, MP2 calls t50, CO calls t50, <font color="#666666">1 fold</font>, SB completes, BB checks.

Flop: (t250) 6[img]/images/graemlins/club.gif[/img], A[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, BB checks, <font color="#CC3333">Hero bets t200</font>, MP2 folds, CO calls t200, SB calls t200, BB folds.

Turn: (t850) 2[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, Hero....

A: Without debating if AQo should be raised preflop, what's my best line here with T1100 behind? Check/fold seems weak since it gives CO an opportunity to take a shot at me with an inferior hand and/or check behind with something like AcTx. On the other hand can I make a real bet here without committing myself? 400 or less stinks since it reeks of weakness, and gives SB 4-1 should CO call.

B: For a moment, assume I am now the button, and bump my AQ to 150 preflop; the same two blokes come along for the ride. Pot is now (t550), check..check.. I bet 400 and get called by CO (SB drops out). What's the plan now if checked to on the turn; pot is (t1350) w/800 behind?
