10 + 1 5k : Two spots I butchered post flop

[HP_Drifter]

Stars 5k, I misplayed both of these hands pretty badly postflop (at least I think), but don't know what the correct line would have been for either.

Hand 1 - I just got to this table, so don't know anything about villain other than we're both about top 20 in chips at this moment. Is my flop raise okay. or should I really be looking to hit something after he calls my 3bet preflop? His tiny bet looked weak, and I was pretty shocked when he shoved. Should I have just called and reevaluated the turn?

Hand 2: I hated this situation. At these limits, the min-raise pre is really often AA or KK, which is why I didn't want to shove. I would have insta folded this if he had made a decent sized bet post-flop, but how do I fold to minbets? I guess I could have gotten away on the turn? Ugh.
