Here are some quick links I can give you to last season where similar things were asked pre-season:
OP for Season 2 which contains an outline of the rules of the game at the bottom.
Basic strategy queston with some helpful links to maybe answer.
Episode Summaries doc from last season, maybe this will help out? It's a birds-eye view of how last season played out, to sort of give you an example of one way things can go. Of course, a lot will be different this season, I'm sure.
I can PM you with more details if you want, but AHoppy might be better for that just because he's moderating this season. I'll do a lot better answering specific questions for you because I can point to things that have happened on the CBS show or the first two seasons of Forum Survivor. Also, Survivor 31 premieres tonight, so watching this season may also help you, many past seasons are available for free (with commercials) from CBS's website, at least for the USA.
That reminds me, if this thing will start in a week, I might want a confessional soon so I can dump my pre-season thoughts.
