white residue on distributor cap/plug wire...
1 point on the distributor cap and inside of the corresponding plug wire is corroded (white powder residue)
What causes this? Why would this happen to only 1 plug wire?

Not sure about the 2nd question, but the answer to the first is "aluminum oxidation".
Go with a cap that has brass terminals instead of aluminum.
