With my limited knowledge, I'll attempt to answer a couple of questions. (You should look at the post above from Larry, it gives quite a lot info on the basics of the program).

First, I would invest in a cheap little kitchen scale to weigh your protein since protein is so important to following the program correctly.

As far as fat goes, Larry gives some insight on that too, but I think that if you need the calories (guess u don't want to go too low) you can add the good oils. BUT it may be that you'll get enough from the protein foods you eat. And I GUESS the point is that we aren't to be afraid of our fat intake (or at least not the good ones) if our carbs (the PP book does definitely start u at 30) are the right amounts. General rule: In the absence of carbs (too many), fat intake should not be a problem.

Others will be able to help u a lot more on your questions, I'm sure.
