What to do with this set?

[iceman5]

When I flop a set in a raised pot, I can never figure out how the hand is affected by there being a flush draw on the flop.

Lets back up for a sec.

Lets say I raise with KK and get called. The flop is T64 with a flush draw. He checks, I bet 3/4 pot and he calls. The turn is a brick. Because of the flush draw, Im much less likely to check behind on the turn for fear of giving him a free card.....fast forward to my hand

MP raises to $30, button calls, SB calls and I call in the BB with 22.

Pot is $120. The flop comes 762 with 2 clubs. SB checks, I check (planning to raise big if anyone calls MPs inevitable bet). MP bets full pot $120 and its folded back to me.

OK. Should I flat call here to let him think I might be drawing? If I flat call, hes much less likely to check behind (like I said I would be in my first example). Then I can check raise the turn and probably stack him if he has an overpair. (I have $950 and he has me covered).
