.035 is right for the plugs. I would switch over to an electronic pointless ignition like a Petronix. It fits inside the ditributor cap and looks stock from the outside, but you never have to mess with points again.
The hood lights are parking lights, headlights are running lights.
Pedal pads either place, maybe your local Napa?
Most flush products are good, just make sure it is flushed out completely before you do the coolant mixture.

Did your state law outlaw split rims. I don't think you should have to replace them unless the rings are rusty and cracked. Try another tire store. Any truck tire store should be able to handle split rims.
