I would raise on the flop simply because of the draw. There probably aren't too many players who do that at these stakes, but he's giving himself the right odds if he has a flushdraw. He might put you on an A and just doesn't want you to make a beefy follow-up bet that would make it incorrect for him to call... plus you are less likely to put him on a draw if he does bet it.
It's not a horrible play to fold on the turn, because you can't beat much, but it's very conservative.
You've already shown weakness by just calling on the flop. There's another reason to make that call.
Again, my vote goes to an information-raise on the flop.

As for the second one, i like your line of thinking but i would've tried a raise there aswell.

The Ace is pretty scary. All kinds of Ax combinations get a piece of that flop, and a lot of players at these stakes will call you down with these hands. There aren't too many other possible hands considering the pre-flop raise.
99 made a set - QQ, KK had you in the first place... leaves the opponent with possibly crap or 77, 88. Not too much there a pair of jacks would beat that would call bigger bets here.
