Those are all spark advance controls for pollution equipment, except for the canister which is just fuel vapour. You need to get it leak tested to make sure it doesn't have a blown head gasket. And also take the radiator to a radiator shop and get it cleaned out. It'll be all gunked up. I'd also pull the whole thermostat housing off the front of the head and give it a good flush out. Flush out the heater core too. Then buy one of those top radiator hose filters when it is all cleaned up, and run water with corrosion inhibitor, not glycol.
