POKE THROUGH ALL THESE (!):

Of these, the Stew-Mac site has a great selection of explanations of what things DO, as does the 1728 site.

Seymour Duncan has a selectable page that spits up wiring diagrams for just about any switching/pickup combination imaginable.

Be warned: all the different pickup companies use different pickup wire color codes, no doubt just to make life unfair. You have to translate the codes for different pickup brands:

Stew-Mac has a perfunctory explanation of how to solder, but you really, really want the Erlewine book too:

There's a few cheap Radio Shack things that make it easier, little alligator clamps, all the tweezers and pliers you can muster, electrical tape, heat shrink tubing, regular old tape to hold stuff in place to solder on, etc. A functioning grasp of common sense is your best bet.
Soldering is more science than art, but Einstein's grade-school teachers thought he was an idiot... he probably was, for a while there. Most people ease into all this by fixing other guitars first. Ask lots of questions. If the first guitar doesn't burn you out totally, by the fourth or fifth one you'll want to try some wiring scheme that has never existed before in the whole universe - it's just a matter of inserting bits of one diagram into another. Electricity is really kind of simple, it just starts one place, goes to a thing that dicks with it somehow, then on to another thing that dicks with it some more, and so on until it pops out the chute.
