Oops. TT, hard decisions for novice

Opponent seems TAG, and his name makes me think of 2+2. Even though he has a nice sized stack he hasn't been running the table over or anything, ~20/8. I'm down 1 buyin at this table. It wasn't lost in some retarded fashion that he would have seen, just from raising and having to get away from flops, slowly dwindled. I don't think we've actually played a pot together since I've sat down. I've been raising a decent amount and seeing a lot of flops, but missing on my good->premium hands. Been folding a lot after the flop. According to PT I had a VPIP of 27% over 124 hands, so my PFR was probably decently high too, ~12-15 or so. Anyone actually like the turn play? What about the river? Is $12 too small a raise PF? It's what I've normally been raising after 1 limper.
