improving my game with pokertracker

[DocOfDan]

Hi

I just recently downloaded pokertracker (After meaning to do so for quite a while) and I have to say that when combined with gametime+ it really is a nice combination. I feel I am making much more informed decisions about entering a hand with marginal hole cards, or bullying people out of a pot.

I'd like to take my game on a little and was hoping to use the pokertracker database to do so.
As such I'd be grateful for any advice on what I should look at in terms of stats.

I read one or two articles which talked about VPIP, BB/100, PFR and WSD

My figures for these are (about 7,000 hands):

VPIP 28.8%
BB/100 3.12
WSD 52%
PFR 7.1%

The last 3 seem fine (according to what I have read), but am I playing too many hands? I'd like to think that the balance of the figures means I am successfully entering with marginal hands and playing them ok. Am I deluding myself?

Are there other stats I should be considering?

Many thanks in advance for any help
