What adjustments do I have to make for pot limit? I'm pretty familiar with no limit and limit but never tried pot limit.

If you and your opponents aren't overbetting the pot much in your NL game, then it's a very similar animal to pot-limt. Some NL games have an overbet for a standard opener. Compared to that sort of game, I suspect you should play more hands in the pot-limit game.

If the pot limit cap causes more hands to reach the turn and river, then position is more important.
