Another tip on the perseverance front: get yourself a cheap audio recorder (I used a Sony microcassette that cost about $20) and record your practice sessions for a week or so. IF you practice consistently EVERY DAY for two months, then go back and listen to those tapes, you will be astounded at how far you've actually come.
I've been playing and practicing for an average of three hours a day for the nearly three years now, and whenever I get a little discouraged, I think, "where was I six months ago?" I'm always miles farther along than I was then. The key is doing it consistently every day, at least six days a week; to pay attention to what you're doing, and to do it slowly enough that you don't make any mistakes. Once you teach your fingers what they are supposed to do, they will take over and just do it.
Something I meant to point out earlier about barre chords, is to practice them first well up the neck; around the ninth fret or so. It's MUCH easier to play them up there, and as you get more confident with them, move them gradually down toward the headstock. You'll be playing both the B and the F in a month.
