Poker Tracker and SNG's

Hello everyone, been a reader on this form for a bit now and I would like to say Thanks for all the good information. Being my first post, please don't beat me up too bad!! I play the 22s and some 33s for the most part. 400 SNGs and a 10% ROI with 38% ITM with some bad downswings thrown in there.. Not the type of performance I am looking for. Anyway, I use Poker Tracker and have about 18,000 hands in my database. Not the largest sample I am sure, but should give me some insight to my game I would guess. What are some of the more important stats I should keep an eye on for SNG play?? Also I was wondering if any of the expert/pros here would have some time and be interested in looking over some HH's of mine. Looking for some input and outside observation of my game.
