For oil, just go with a 5w30. I like to run the high mileage oil blends in mine. I have just over 100k on mine and it runs great on that. I would avoid synthetic at this point unless it has been run in the car consistently. Changing over to synthetic with 115k on the motor wouldn't be advised. A quick google search will give you loads of horror stories about that. As far as plugs go, autolite 25's are fine. If you're doing a tune up you should also consider your wires if they aren't in good condition, cap, rotor, and pcv valve.

autolite 25's and any 5w or 10w 30 non synthetic or synthetic will be fine. nuff said!!!!!!!!
