For bearings you will need:
10 X 15 = 4 ea, for inner hubs front & rear
5 X 10 = 4 ea, for outer hubs front & rear
5 X 8 = 4 ea, 2 for each differential
4 X 8 flanged = 4ea, for steering mounts
I would get a set of adjustable turnbuckles, I personally ordered metric ones made by Lundsford, but it has been posted that some b3/b4 combinations work.
Depending on what you are doing with the car, I would look into replacing/upgrading the shocks that come with the car. At the very least, replace the springs.
The slipper is a must in my book.
I set of u-joints for the rear couldnt hurt.
Extra rims are always a must in my book also.
(my book is getting heavy to carry, lol)
Hope that helps out some. Good luck with the car, it is a great platform.
