Well, one of the best things to get would be a Helms Shop Manual. It goes through everything step by step w/pictures. Yeah, 80 might be a bit much on a book, but it will be one book that you will read over and over, and will actually pay for itself after you use it a few times.

But just start w/small things like oil, spark plugs/wires, new intake, and slowly you will get better.
