I think you can bet bit smaller on the flop.
With 0 read I would just fold to the raise, it's a bit painful but you have A high with no possibility to improve to a nutted hand.
Preflop
Out of position I prefer to isolate a bit larger to at least 10k or 4BB.
Flop
You pretty much missed completely here, but you still have some showdown value. I prefer to start defensively with a check. If he check back, its great, and if he bet, then you just make a decision. Probably call a small bet but fold to a large one. As played its annoying to fold to a min-raise, but its to expensive to continue, and you dont have enough ways to win this pot.
It seems OK until you get raised. It is really exploitable, I would would fold to the flop miniraise at those stakes. You could call and see if he bets and if you hit on the turn. You could get totally pushed around folding to raises of cbets, but I don't think people know to do that at these stakes.
