Need some help please.

If I were planning this trip, I would start by carefully checking everything rubber. Tires, wiperblades, hoses, BRAKE LINES, etc.

My list of stuff to do before I left would be to:
Drain tank and add a new sock.
New belts and radiator hoses.
Inspect the brakes carefully and add new brake fluid.
New tires.
Battery.
New fuel pump.
New oil and filter.
I might rebuilt the carb if time allowed. I would at least take a carb rebuild kit with me and a can of good carb cleaner.
Make sure the alternator is charging.
New plugs and wires

Things I would take:
Tools
Jumper cables
Fluids
Jack and good spare
Extra money
Give yourself an extra day or two for the trip in case something goes wrong and you have to stop somewhere and fix something.
I like the fuses, wire, and duct tape idea too.

OK, obviously I'll want drive it around for a couple days to make sure she's doing ok and I'll probably do a bunch of other stuff like bleeding brakes and maybe new plugs
I think doing everything and then driving it around for a couple of days is a fantastic idea! It will give you a good feel for the car and help to build your confidence in it. Hopefully if anything is going to go wrong it does it during these 2 days.

Plan your route and see if you can locate a FABO member or three on the way just to check in with. I'd give you a free bed and a place to park your car but I am in San Antoinio.
