1962 C-10 w/ 235 - 1st Oil Change

[bloody hammer]

I'm finally getting around to changing the oil in my '62 C-10 and it will be the first time. I've changed the oil countless times in other vehicles but never on one with the cartridge type oil filter. Do I drain the oil directly out of the canister? Or just let it run back down through the engine to drain?

After I refill the engine do I need to pour a separate quart directly into the canister with the new filter? Or do all 5 quarts go right into the engine?

Engine is a 235 and I'm going with 10W-30 (which is just a guess on my part).

Any and all advice is appreciated.
