Jason,
First, Welcome to the "BOLT", there are a bunch of great folks here to help you along with your project. Be sure to check in on the Southern Stovebolters Forum, there are quite a few guys in Florida.
Second, I don't believe I would peruse the S10 under your 59", the Task Force trucks are wider and require a larger chassis, a 73' and up 1/2 ton would be a better choice. The parts are available everywhere and they came with most of the upgrades you would want to do, IFS, power steering, disc brakes and so on.
.
Personally I decided to stay with the original frame, parts are available to upgrade the suspension or modify the stock axel. I just couldn't bring myself to cut the frame so I choose to stay with a straight axel. Power steering and disc brakes can be added easily. Most modifications should only take a few days and allow you to enjoy your truck while you work on it.
Just a note on going into a complete teardown, "DO YOUR HOMEWORK". I can't stress that enough, I didn't and have had to live with the lessons learned the hard way, I have lost out on a lot of time being able to enjoy the old truck. Just my thoughts. In the end it is your truck and it should be built as you like, it's a great adventure.
