spark plugs: NGK makes some good plugs, and so does bosche.
wires: the wires does not matter what kind you get. i just get what autozone gives me. except the REALLY cheap ones.
cap: does not matter.
now if you plan on getting a bigger coil then you might want to get some heavier wires and a platinum plug. other than that if you are running stock then i really would not worry about much.
