I have just purchased Pokertracker and so far I have only put in 838 hands.

My stats for these hands are:

VP$IP = 20.17 %
W$WSF = 29.49 %
PFR% = 3.34 %
W$SD = 62.22 %


How can this tell me if my over all strategy is good?
What values would a good player have and what should I try to improve first? What values do you guys have?
