man, if I were you I would get a chilton's manual and at least give it a try. You take the serpenine belt off, take a few bolts out, loosen a couple of hose clamps and that thing should come right off. I'm sure if you bought a pump it would come with instructions on how to prime the pump.
found this info online for you. It was off a chevy van,but I would assume it would be the same proceedure:
Get a 5/8 flare wrench to take off the high pressure hose and a screwdriver to take off the low pressure hose. Drain out fluid. Then you'll have to get a pulley puller to pull off the pulley. Once off the mounting bolts are exposed for you to take off the pump. Be sure to check brackets for cracks. Mounting is the reverse of this.
