One of the things that I would like to do is add a linear current and
voltage regulator.

I found a very straightforward schematic in this PDF file

http://igor.chudov.com/projects/PP-1104B-G-Power-Supply/Linear-Voltage-Regulators-NatSemi.pdf

on page 12. It seems to be adjustable with pots for both voltage and
current and could use my Darlingron transistors that I already have.

Am I missing something and is this schematic a sensible one?
Applications are voltage up to 35 volts, current up to 100 amps (but
at much lower voltages). See description of the PP-1104B/G for its
capabilities.

I missed seeing the pots. That paper is really about what regulator IC to choose, rather than instruction on making your own regulator from discretes.

I would suggest getting an ARRL handbook -- they'll have a chapter on power supplies, along with some practical projects (but not any that go to 100A!). That should get you started, although you'll find out lots of interesting things about operating at 100A, I'm sure.
