You can probably get away with not replacing anything at all - I'm guessing a quick soak in vinegar and some elbow grease with a scouring pad or steel wool will clean those parts up nicely. If you use steal wool, be sure to wash with water and a sponge after, you don't want to leave steel particulate in there.

Oh, and this might seem counterintuitive, but when you put everything back together, maybe give it a spray-down first with WD-40 - it won't really bother the electrical connection much as long as you reassemble everything tightly, but it'll hopefully avoid future corrosion.
I'm worried that the resistance through the corroded external connector is causing the periodic drop of voltage to the Valvetronic/DME. You can't see it in the photos, but the plastic of the external side is completely cracked from the expansion caused by the corrosion underneath the plastic.

Going to try the wreckers tonight....
