With some careful shopping, I got the electrical manual for $20 and the mechanical manual for $80, delivered. Both were sold as used, but I can't tell they've ever been opened. Original Ford issue, too!
After looking at some CJB videos on youtube, I'm thinking about going for a four hole block ran directly off the battery. I bought a battery isolator and am waiting for my next "rocking chair check" to buy an auxiliary battery. I hope to have the interior done by August ( light show, Pioneer touch screen, four way front door speakers, three way rear, back up camera).
