As far as the spark plugs, I recommend you use a factory Autolite brand plug. The OEM brands always seem to work the best. HOWEVER, I have a concern. These engines are pron to problems with removal of the plugs and actually the plug blowing out of the head due to a shallow thread on the plug. You may want to have the work done by someone who has experience and the tools to retract a plug that breaks off in the head.
As far as the oil, yes, 5w20 is what you should use. As far as brand, they all are required to pass the same API certifications, so any brand (Valvoline, Pennzoil, Gastrol.) Are good. In my personal vehicles, I use Pennzoil.
