resources for limit tourneys?

[Yossarian147]

I'm considering entering Commerce's LAPC $1000 limit event this Friday. I play pretty solid cash FR limit but I'm not sure what strategy changes are required in a tournament environment, and have never played a live casino tournament before. Any books/links/info appreciated.

My thoughts are that in the early rounds it plays very much like a cash game since blinds are small relative to stack sizes (t3000, blinds 25/50). How much does M become a factor in later rounds? Obviously you have to push more with more marginal hands but I'm looking for some guidelines.
