playing raised pots OOP with decent hand

I'm wondering what other people do with a hand like TPTK or an overpair when they are in early position in a raised pot. I frequently find myself in situations where I don't figure out my opponent has me beat until I've already built too big a pot to fold. Here are a couple sample hands (not necessarily hands where I'm beat), but any general advice would be helpful.

Preflop: Hero is UTG with A[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/heart.gif[/img]. SB posts a blind of $0.10.

Assuming opponent is typical 25NL player, what is your plan for the rest of the hand (and what, if anything, should I have done different earlier)?
