set on flush draw board - your bet?

[AceofSpades]

I play six max a lot and I'm pretty sure that I'm not doing it the most profitable way, so how does everyone else bet when you flop a set on a board with two suited cards in a cash game?

What's your play if:

1. You bet half pot, and are raised
A) Pot raised 4xBB preflop
B) Everyone limped

2. You bet the pot and the turn makes a flush possible?

Thanks,
Joseph
