Mitch,
I would just replace the roof mounted "antenna up" switch-- they are only a couple of bucks and if it has gotten water in it, it is not worth trying to repair. Just remove and take to any store that sells parts for home alarm systems. They can tell by looking if it is a normal open or normal closed switch.
And for the "under coach" connections such as oil pressure and water temperature, your approach is correct: clean, sand metal with 1000 grit if you don't have a clean metal surface (or replace the connector). Then apply dielectric grease and get a good tight connection. You don't need to get messy with huge amounts of grease, but coat all the metal. Basically, you are isolating the sender(s) so that muddy water will not provide a partial ground path and trigger an alarm.
