Villian certainly isn't showing you much of anything and without reads he holding exactly two cards. If he's a calling station (which is what it looks like) he could be sitting on any pair and is not going to fold it out to a single bet. He's been calling the whole way anyhow, no reason to think he'll change that now.

This isn't sure. And I don't know why you assume that this opponent will call down just because he saw the flop. Bet the flop! And IMO a follow up on the turn is correct.
