55$ pokerstars 1table SNGs questions

[Percussion]

I've been playing them, and I have a few questions -- First of all I own Pokertracker, and am moving from rings. What is a good way to be able to import my tournament histories into PT?

Secondly, a few tough situations--I have KQo in UTG+2 7 handed blinds 50/100 w/ 1200 in chips. Sometimes I fold, sometimes I limp, and sometimes I raise to 250--who likes what the most?

Secondly, what blind to stack ratio do you need to be stealing the blinds with suited connectors like J9s or 78s from the cutoff? I usually will triple it w/ t1200 blinds 25/50...

Bubble play: 4 handed blinds 100/200 and I have 1.5k to 2k in chips, and there is another stack exactly my size. What range of hands do you push with? I go 77+, AJ+ KQ
