Hand 1: I think you need to bet out on the turn. Too many players are going to pick up on your weakness, and buy the pot with a pair. If you get reraised, you simply let it go. If you get a call, you value bet the river and let go to a raise.

Hand 2: That raise is going to end the hand 90% of the time. I'd call and bet out on the river.

Edit: BTW, limping in early position with JJ seems very correct in these games.
