The factory service manual is the only manual to speak of. It's geared toward service tech work, so it's very helpful for troubleshooting stuff like the factory electrical system, or replacing an alternator, but not helpful for figuring out how to install an aftermarket rad or fab and duct intercooler piping.
I suggest if you want general how-to information, that you buy a good general automotive how-to book. I can't suggest one since I don't know exactly what you're looking to do, what your level of experience is, what your technical background is, and if there is a single book that will cover all that you want. But I do know good ones are out there - I suggest that you spend some time at a Barnes&Noble and check out what they have.
