Embarrassing, but just last month I finally started working on this again (three moves, new job, etc etc). Also, I misspoke, the car is a 67. I'm going to provide some pictures and some updates on what I'm doing/thinking.
I'm going to find someone who can do some sheet metal work for me because I'm planning on replacing both lower rear quarters, and both door skins. After sanding down the doors yesterday, I exposed way more Bondo than I think I want to tolerate. The only part of the car I haven't sanded down past the red yet is the rear where all the curves are that my sander doesn't get to very well... man it's a lot of work. I have a 400 hood that is already primed (bought separately) so I don't have to do much with that. I have fenders at another location, but I think the lower part of them will have to be replaced.
The car originally had a 400 "WZ" engine in it (4 speed), so I've been passively looking for one. There's one listed not too far away from me here http://sfbay.craigslist.org/scz/pts/4851181279.html. The car has some pontiac wagon motor in it now which runs like a champ, so I'm weighing whether or not it's worth it to me to shell out a couple grand to have the original engine.
You may not be able to see it because of all the red paint dust, but the metal on the inside of the car has been cleaned up and painted with POR15.
Again, I'm a total amateur so feel free to point out things I might have (probably have) missed or just doing plain wrong.
