Autozone sells a cap and rotor that are brass and they do fine for me. Just tell them you want a brass cap and rotor and they will know what you mean.
I use Autolight #25's in my Stang. Autozone will know what you mean here too when you tell them to give you Autolight #25's.
If you still have the original set of wire replace them as well. Go with a good brand of wires like Taylor or Ford Racing 8mm or 9mm wires.
As for oil I use Mobile1 tri synthetic and a K&N oil filter. This makes for some very expensive oil changes, but my car loves me for it. I just know it does
