Use the eraser on a #2 pencil to clean them

Maybe clean up the contact points with some acetone on a Q-tip first, then the eraser. Also, as far as lamps with twist lock bases, it helps increase and maintain contact with the board if you re-spring the tabs. Just bend them gently outward with a little screwdriver.

Going to work on the printed circuit tonight, after cleaning everything should I use die electric grease on all the contact points for the bulbs and the connector?

I don't think I would. Grease will just help attract more dirt and you shouldn't have to much problem with corrosion in the cab.
