Ledom is right - the exercises in the BFL book aren't very complicated at all - they're basic weight-training exercises.
What I do is practice the movements at home first (I don't have weights at home - I just 'pretend' to have the weights in my hand and practice the movements). You can also try making a photocopy of the page(s) and then shrinking them if you have access to a copier that does that. I carry one of those small sprial memo books (3x5") with me to keep track of my workouts, sometimes if I'm learning a new exercise I'll draw little stick figures and write some simple instructions/reminders. At most it takes 1-2 times of performing the exercise to memorize it - but that's just me
Congrats on quitting smoking!! If you're just beginning to do weighttraining, BFL is probably one of the best programs out there to get your feet wet - just give it a whirl and commit to 12 weeks - you'll love it!
