Hand 1: bet/call this river. There's too much value from any any pair on the board. A rivered two pair might even raise you. You're playing scared though when you check this river because of a possible gutshot that just hit, especially when the villain bet out on the flop.

Hand 2: Not a lot of hands you can beat now, but you answered your own question if you're behind 60% of the time. The pot is laying you 15:1 to make the crying call here. You have to be good less than 8% of the time for this to be +EV, so easy call.
