Firstly, you're playing $25NL if you want to be playing hands like 75s I suggest you buy in for 100bb.
As played, I fold pre with your stack size, and raising is still better than calling. If you're gonna check the flop then check/raise, you have 13 outs and so you don't mind getting the money in plus he will fold a lot of the time to aggression on the flop. He's laying you nearly 4/1 on the turn and you've missed your draw so I probably just flat here, and on the river you've not even bet half the pot, if you think your villain is weak you want to be betting at least 80-85% of the pot, though I probably concede the pot on the river, a raggy ace is the least of your worries consindering he called your turn raise given that it's a limped pot.
Personally I lead on the flop, and re-raise big if raised, note having $14.75 on the table playing like this won't do you any favours
