All the above is great advice and I'll add that the service manual is a must even if you aren't going to do all you're own wrenching. You will just learn so much from that manual about your ride. The parts book is also good with exploded pictures on how things go together. I would also like to say you won't get everything done to the bike in 1 round. It is a work in progress and you'll probably be adding or changing things in 2 years time. This is all part of the enjoyment of a Harley, so many options to chose from.
