YOu definitely should reraise PF and put this guy on a range early. PF decisions are usually cheaper and involve smaller pots than post flop ones. If he just calls you have position on him, he'll most likely check into you on the flop unless he has you destroyed.

If I had played the line the way that you did, I would have thrown out a small test bet there if you're really confused. What this will do, is a few things...
1) he'll fold (he has you beat with a flush...i think a set lead bets the turn)
3) he'll just call and then check into you on the river (optimal)
4) he'll just call and bet into you on the river, in which case iyou pretty much know you're beat
