Well, I've got my truck back from the shop, and back to my house. It was a 3 hour drive, on the interstate, 60-65 the whole way (a few times going 75), and I must say, it drives like a dream! I was mistaken on what was leaking regarding the power steering fluid. I thought it was the pump, but it was actually the pump, the lines, and the gear... most specifically the gear was the worst offender. That is what he was referring to when he said the 'whole system'. Does that sound right? It would involve removing the belts, taking off the old pump and replacing that, and then taking off and replacing the power steering gear, which I believe is fairly expensive.
In any event, I was able to drive 175 miles at high speed and the truck handled like a dream. I would love to get a sway bar or something to make turns a little less... bouncy. I have a laundry list of items I'd like to address, including new headlights (way too dim), aiming the headlights (pointing down due to the adjustment screw bracket being broken), new dash pad, new seat cover, carpet, check the idiot lights for functionality, replace the sender units, replace a few deteriating parts, correct the abysmal stereo install, etc. etc.... I've got a long way to go!
