I like using platinum plugs because of the 100,000+ mile change intervals and I usually just buy a good quality plug wire. I think the ones that are on my '88 Escort are the best quality Auto Zone brand. They have a lifetime warranty too. If mileage has dropped that much you should check your 02 sensor, I have had them go bad before and my mileage would drop about 25-30%. The car probably came from the factory with platinum plugs and shouldn't need changing yet.
