Default 2004 LE Turbo missfire/ pinging

I have a 2004 PT Le turbo with automatic. I have noticed a miss at idle and a bog/ ping while accelerating. The engine light comes on and goes off intermitantly.
Tonight it was on and then flashed for about 10 seconds and then stopped flashing, just stayed on.
From what I've read here, it sound like it's time for plugs and wires. What type wires and plugs? And what is the correct gap. BTW, car has 28k miles on it. Can I do this myself? Or what should it cost to have it done? Any other suggestions? Modern cars scare me when I look under the hood.

You have the aluminum intake manifold, which is the easiest for plugs/wires.
The stock Champions aren't bad, you can get Good wires from RaceAndStreet.
Gap at 0.040, and use anti-seize on the plug threads (dab) and dielectric grease on the plug boots.

Okay, I replaced the wires with some Magnicore blues. The only plugs available at the local Auto Zoo were autolight AP5263. I watched them gap them at .040. Now the car runs worse. If I stomp it at a light or at low speed I get sputter sputter sputter ZOOOOM. I re- checked all my conncetions and they're all good. I am also noticing what sounds like valve clatter. WTF? NO codes, either. Should I just take it to the stealership? Do the wires/ plugs void my waranty? HELP! this is my only car.
