Hey there...if you go to the LWL forum (which had its genesis as a BFL forum, incidentally) you'll find a sticky thread called "Basic Bodybuilding Information" which includes a "Basic BFL Info" thingy.
Quick answers to your questions: 1) Yes, and yes the book has instructions, no video; 2) either gym or home, whatever works for ya; 3) yes, but it's YOUR intensity level; 4) Shakes, bars and supps are optional - real food always works best.
