I suggest the Tao of Photography as a book about the philosophy of photography rather than the nuts and bolts. You can learn more about the technicalities of photography as you go. Put your F100 in program "P" mode and just shoot. I love my 50 1.8 on my N80. It's very sharp.

My local lab will process a roll for me for $6 and put it on disk for $3 and they do a very good job. Don't take your film to 1 hour places unless you like scratched negatives.
