There's no short answer to your question. If you post some hands in the Hand Analysis forum we can try to look at it there.
What your percentages "should be" is hard to say, but good players typically have a VP$IP (volountarily put money in pot) ~18-20% of the hands in full limit games, and raise preflop ~10%. This is in the long haul, though. I've had nights with VP$IP of close to 30 and some others where it's been below 15%. It's also, of course, dependent on your opposition.
While looking at stats like this might be helpful in finding potential leaks, it should be used with caution. If you ever - ever - consider folding a hand because you feel that your percentages may be off, then you're barking up the wrong tree. Fold a hand because you think it's not worth playing. Work on your winnings, not on your percentages.
