General Late Game Help

[warrantofice]

If somebody could just explain to me and/or give me some general guidelines for late tournament play, I would really appreciate it.

I make it deep occasionally in tournaments but my majour leak comes in when the blinds and antes have the stacks around 8M or so. I need to learn how to steal but i just seem to pick the wrong times. Should i not be stealing? What sort of hands should i steal with? Whats a good position to steal from? I guess assume that the table is somwhat passive, and its a $24 buy-in FTP tournament.
