Pre-flop:

It sounds like you're taking the concept of implied odds with deep stacks a little too far. Calling 34o after a raise is most definitely not profitable. Hands like 67s, J9s, and 44 are certainly worth playing in position, but don't get too carried away with it. Keep in mind you are only as deep as your opponent, so if he has $150 and is raising to $15, those suited connectors lose quite a bit of their value. Fold more.

Post-flop:

If your continuation bets are getting called and raised too much, the simple answer is to do it less often. Pick the spots where you know your opponent is tight, and won't raise you without the goods. If they call too much, that's certainly exploitable also, you just need a hand to do so.

I have some of the same tendencies in live play, and when I catch myself playing like this I just try to remind myself to be patient and play TAG.
