I play NL20 on Titan and it's the same game you've described. As the_main said, value betting good hands gets the money.

You don't need to play scared play scared befor the flop because cbets are not very efective. Just don't cbet without a hand into more than two people. I would also be useful to try to identify who will fold to a double barrel and attack those players.

As for the pre-flop questions.

1. I limp most of the time with PPs up to sevens in early,middle position. A raise from time to time is ok, but you need to keep in mind that you're trying to get the right odds to flop a set.

2. AQ, AJ type of hands in middle position deserve a raise I think. You're clearly ahead of their range and you need to make them pay to draw, plus you need to thin the field with these hands. I think you'll get a lot of value when you hit against people calling with dominated hands.
