Bet and raise more $$; your bets with less than AA are weak and exploitable, especially when you are min 3betting a min bet open. When betting post flop.you should be betting a higher percentage of the pot; 2/3-3/4 pot for most hands. You risk more, but you disguise your better hands, elicit a few more folds and charge draws enough to make calling unprofitable. Your 3bb open is fine.

Add checkraise for 3bet pots with top pair if you suspect opponent will fold to a bet, but will lead out if checked to. (You said you thought opponent was weak in the A2s hand)
AQ hand; without a specific read that this guy only leads sets or overpairs, a reraise is in order against that donk bet. It is likely opponent has one weak pair or air here. Reraising most opponents in this spot should show a profit. If opponent continues in the hand then consider checking or folding.
