I've got a month off to work on this project

, and I've burned up a week trying to figure out how to avoid making another mistake! LOL Sure is a ton of knowledge here, but I can't seem to find what I'm looking for for my year truck.
Can anyone give me a suggestion as to the best sources for the following?
A power steering set-up? I found great stuff on how to convert it, but not much on what parts to find to do it the cleanest and easiest...
A tilt column, preferably w/o shifter handle?
6-lug front disc set-up? I want to keep my wheels, but power brakes would be really nice. I found an '87 and an '88 GMC with 6-lug front discs - will they work?
Thanks for your help, guys, and thanks for the welcome!
