The fuel exhaust canister send unburnt vapor back to the engine intake and droplets into the fuel tank.
The VCV on the T-stat is a heat actuated (by coolant temp) vacuum switch to control/divert vacuum to the vaccum advance on the distributor.

No, it is not needed, all that is required to run/drive is vaccum to the distributer advance and to the brake booster. There are alot of varying opinions on the emmisions equipment and the link posted above by fmc400 shows that.
Your dist advance needs to be hooked to a timed vaccum source, you don't want advance at idle,

Great info I really dont understand the vacuum sytem that well with all this emmsions stuff!! If I remove the fuel canister do i need to cap the vent line from the tank!! Can I take vacuum from the carb for the Dist?
Still trying to track down a basic vacuum diagram that will show me the minimum hook up required to run the heater and air ( and of course the basics Brake booster and dist...)

Yes, that is the best place, one will have vaccum at idle, you want the one without vac at idle, I am having a brain fart at the moment and I can't remember the positioning of the ports
