To paraphrase a homebrewing guru: relax, don't worry, have a mead.
I don't know about books, but read the posts here, buy some honey and make a batch of Joe's Ancient Orange (also known as JAO on the forum, and elsewhere). Keep it as simple as possible to begin with. Start with a one-gallon batch, that way if it goes south, you haven't lost much.
Remember, humans have been making mead for literally millennia without hydrometers and pH meters and fancy carboys.
