I'm shocked you folded Hand #1 lotta. Small pairs are very valuable in raised pots. Though you were out of position, you stood to win a stack if the guy has an overpair and you hit.
Though, you really should have a full stack in front of you to make these hands as profitable as possible.

I have NEVER folded a small pair preflop out of fear of being set-over-setted. They're only folded when someone's preflop raise is too big to call profitably.
