318 rebuild, whats the best combo?

As far as you ignition goes, that should do it. You already have the MSD coil, MSD 6AL, and electronic distributor, and you should have an ignition system that should be good enough to fire even Bretts engine. If you get to that level all you might want to change is to get the MSD distributor #8534. You can check out all the MSD stuff here:
