Many of us here have done Body for Life or similar programs. It was my introduction to a structured weightlifting and nutrition program. I did 2 challenges, more or less by the gook, before branching out and experimenting with different approaches.
I think for your goals of gaining muscle, it's a fabulous program. From your stats, it looks like you don't need to lose weight, but want to change you body composition. BFL is a great way to do that. Don't be surprised if you actually gain scale weight and get smaller. When I did my first 12 week challenge, I gained 2 pounds, lost 8% body fat, and went from a tight size 6 (US) jeans size to a loose 4.
Usually I tell women who are using BFL to lose weight to do more cardio, but I think in your case, the original plan would work.
Be careful of the free days- for many of us it re-triggered old binge eating habits.
Have fun and stick around!
