Jeff,
The thing about lenses is that each manufacturer had its own system for assembly. In general, there are likely to be a couple of threaded rings holding the whole thing together--one on the front and another on the rear. Typically, these will each have two slots or holes directly opposite each other to permit you to use a spanner wrench to turn them. Get a good spanner wrench (like the micro-tools ones) and not a cheap one. I always work on a small tray to keep parts from rolling onto the floor, and I always put a cloth on that when I'm working on a lens. Keep a notepad and pen handy to write reminders for reassembly. I learned from some professionals to use Glass Plus exclusively--it works better than any of the expensive lens cleaners and doesn't harm the coatings.
Many of these lenses are simple designs, especially ones that don't involve shutters. Usually they are composed of two or three elements. I typically remove the front element, clean it carefully with a clean cloth and lens cleaner and then set it down to dry for a few minutes. (You don't want to trap moisture between the elements.) Then I replace the front, remove and clean the back element, and reassemble that. Taking the entire assembly apart at once just increases the chances that you'll forget how it goes together. If there's a middle element you can clean it from the front and the back without removing it: just put a piece of cloth over a cotton swab and clean it with that.
Offhand I can't think of any good books or posts, though I'm sure there are some. I rely on a pretty good mechanical understanding and the knowledge gained from having messed up a lens or two and learning thereby what not to do.
By the way (referencing the joke post in the previous reply) sometimes a yellow shift in lens color can be corrected by exposing the lens to sunlight. The trick is to put a piece of aluminum foil on the back of the lens and open the iris all the way (and the shutter, if it's part of the lens) and place the lens in sunlight (facing the sun) for a day or two, checking the color periodically as you do so. I'm sure this doesn't always work, but I don't know of any other purported cures.
