Two poorly played hands, did I fold the best hands?

[FreakDaddy]

HAND #1
No read on villian. After 15 hands he was 42/10(PFR)/2.5(AF)

Table was generally tight. Could I have raised more pre-flop? Yes, but it's not that big a deal here. People were folding to 4xBB raise and I was about to leave. Any ways, I thought for a while about raising the turn, but decided to flat call. River smells like villian flopped a set (likely 4's), but does anyone call this? I'm not a fan of going to the felt with KQ or one pair for that matter.

HAND #2
Please no comments on mini-raise. I should have raised at least 4xBB, but didn't. Other comments appreciated.
