Looking for help understanding Holdem Indicator please

I am trying to understand what to look for when looking at the player stats part of Holdem Indicator. I am sure that it is all important, but what stats should I be looking for the most?

Is it:
Vpip
Pfr
Af or Wsd/W

I am brand new to your site and also wanted to take a fast second and say hello and thank you for such a great place to read up and talk about a great game.

PS: Yes I used the search but was unlucky in finding an answer to my question.

The first three you mentioned (VPIP, PFR, AF) give a good general idea of the opponents` style and are the ones most commonly referred to. Be aware that they don`t necessarily mean much until you have 40+ hands on the player in question, and 100+ is better.
