I would do AC Delco sparkplugs, sparkplug wires, pcv valve, air filter, fuel filter.
Spark Plugs $30
Spark Plug Wires $35
Pcv Valve $3
Air Filter $15
Fuel Filter $13
So thats like $100 in parts and 2 1/2 hours of labor.
I don't know what there hourly rate is a hour but like 80 to 100 should be normal. So it should be about $350 im thinking. I would request the cheaper but middle of the road wires because thats where the price goes up alot but make sure they use AC Delco plugs.
