On your original question:

1. Mid pocket pairs in EP - I'm assuming you're talking about SNGs here. In SNGs, limp pocket pairs 22-TT when the blinds are low (say level 1 and 2), and call raises if you can win 15x the chips you need to call. From level 3 then tend to fold the lowest pocket pairs (say 22-66) from EP depending on your stack. Just remember that you are playing to flop a set, and if you don't, then generally tend to shut down to action on the flop.

2. Playing a strong hand on a 2-flush board - Say you have TPTK and the board comes 2-flush. BET BET BET! No need to go all-in though - tend to bet 3/4 to full pot - if opps have a flush draw then in general they are drawing against the odds. Just remember that you may need to overbet the pot if you are first to act and there are multiple opps seeing the flop because the odds for each subsequent opp get better with each previous opp that calls.

3. Playing strong overpairs (TT-KK) - Generally tend to bet these hard since opps will call you with hands that you crush. Eg. if you have KK, raised preflop, got 2 callers and the flop comes J93 rainbow, BET BET BET since AJ/KJ/QJ/JT top pairs, QT straight draws and even A9 and A3 will call your bets when they are drawing to 5-8 outs at best.

One thing that David Sklansky said about poker was that it is a game of trading mistakes. Whenever your opps chase draws against the odds they make a mistake and you win. Read that over and over again because it's really really important. You WANT your opponents to chase their draws against the odds because YOU WIN WHEN THEY DO. Sure, when they hit their draws it can be frustrating but you can often shut down if the draw gets there and they give you serious action.

Don't you see the point that they are making a mistake and losing money to you by calling your preflop raises with T7 since they're only 2.2% to hit two pair on the flop?
