1/2 NL, 50BB buyin strategies - TPTK

So,

I previously had a post about a trip coming up to atlantic city where I plan on playing 1/2NL with about $80-$100 to start.

We covered most of the preflop strategy, but I'm curious about general post-flop strategy.

Am I letting go of TPTK in any decent sized pot?
Am I letting go of overpairs anywhere?

Examples:

Hand1:

Hero dealt QhQc, raises preflop to $10
gets 2 callers

Flop comes Ts 8s 3d

Hero makes PSB
Villain raises a good amount (2-3bet)
Other player folds.

Hero ???


Hand 2:

Hero is dealt AQ,

Flop comes Q T 2
Hero bets,
Villain raises,
Hero ???

Basically, I want to know how to deal with TPTK or overpair situations in these types of games in the following situations:

(1) in position after a pot sized bet w/ light draw board
(2) in position after a pot sized bet w/ draw heavy board
(3) OOP w/ light draw board
(4) OOP w/ heavy draw board

Thanks
