Should I bet at this high flop LO8/B?

[Vee Quiva]

1-2 LO 8/B at Party Poker
I'm in Big blind with T [img]/images/graemlins/diamond.gif[/img]Q [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/diamond.gif[/img]
3 callers and small blind completes, I check.
5 small bets to flop

Flop: 9 [img]/images/graemlins/diamond.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/spade.gif[/img]

Check, I bet. One call, and everyone else folds. Heads up to the turn for 3.5 Big Bets

I bet to make the low draws pay to draw. Should I have checked to try and pull more people in with my flush draw?

I bet to keep pressure on. Opponent Check Raises. I call hoping for a diamond.

I check, Opponent bets. Should I call with low end of the straight?
