Of the several manuals available, I would say the Haynes is definitely not the best. Get a Clymer Manual, and download a factory manual(they are posted on the internet). The factory manual is for earlier models, but there is a lot that is common between them.
There are also excellent videos on YouTube most notably by an excellent mechanic with a rather foul mouth named Chris Harris. Lots of excellent info peppered with F-bombs in his videos.
It's great that you have it running. With a bike like yours that has sat idle for a long time that is about half or more of the battle. Check the tank ASAP, and if it's clean, dump some Techron Fuel System Cleaner in it and Start a regime of starting and letting it idle for 5 minutes everyday until you have all the maintenance checks done and she is ready to get out on the road. Be aware that it will probably run crappy for the first couple thousand miles. They seem to take that long to get all the cobwebs blown out.
Once you have it running on the road, you can strip the bodywork and clean up the corrosion and do some repainting. The rear frame tube under the seat and cowl will be really bad, probably the worst part of the frame. Take your time, you have a really great bike there that will give you many years and at least 100,000 miles of pleasure.
