$22 NL Holdem SNG's (Need ITM Advice)

[PokerProdigy]

I have been playing the sng's for awhile now, and I feel like I don't play very well once I get in the money. Where can I find some good advice about ITM strategy? Specifically, I am looking for advice about what to do when there are exactly 3 players left, since I feel like my heads-up game is ok. I already know the general advice to "gamble for 1st settle for 3rd," but this hasn't done me a whole lot of good. I am looking for one of 2 things to take my 3 handed game up to the next level:

1) Something more structured at first (like a basic strategy I could follow).

OR

2) Advanced ITM strategy so I could further my understanding and really get good at playing 3 handed and evaluating the situation.

Basically, I am just looking for something to give myself an edge when 3 handed, so any personal tips or links to discussion of this topic would be greatly appreciated.

Thanks,
