I actually recommend sticking with the OE Champion plugs. I had bought some basic copper plugs spec'd by the parts store (NGKs I think), and they ran fine for ~10,000mi. After that I developed a terrible misfire. Felt like the truck burned another valve.
I picked up an OE Champion set from the dealer, and compared the new plugs to the old ones. There was a noticeable difference in the height of the center electrode; the Champion plugs had a taller electrode that stuck out further. I was surprised to see the difference!
I went ahead and got a new set of Mopar plug wires, cap, and rotor to finish out the service. Figured I'd stick with OE stuff this time around.

When I changed out my plugs and wires, I used a set of Autolite platinum plugs and an Accel distributor cap and rotor with brass inserts. For plug wires, I picked up a set of Taylor custom fit 8MM wires from Summit Racing. Since the cap is way in the back and no fun to change, I really wanted the brass inserts in it for longevity.
Also, be sure to get rid of the spark plug heat tubes that are pressed into the head if you haven't already. They serve no good purpose at all, other than to collect dirt and debris around the plugs and allow them to rust out.
