There's no reason to pull a stop 'n go on the flop.

You have what is probably the best hand, but it's vulnerable to probably 1/3rd of the deck against a reasonable range of hands that the villain could have.

3bet if only to take control of the hand. If a club falls on the turn, i probably check behind and then call 1 on the river unless i fill up or the two pair gets counterfeited.

With how the hand wound up, both the turn and river looked safe. Raising the turn is fine at that point.

You have to lead out on that river too, i think. Your hand will be called by many hands that you have beat. The problem is, when you did the stop n' go, you're showing extreme strength that for him to check/raise the river on you there, there's almost no way that you're ahead. The fact that the pot is so bloated at that point hurts. Unless he's been acting maniacal, though, I might be inclined to fold.
