Hmm, hopefully you have a different truck than mine as mine has an A/C component blocking two of my plugs. But all in all don't get discouraged masking tape and a sharpie go a long way. As for plugs there are alot of choices, you can go with the stock plugs, or you can go with the multi point plugs avail. today I went with the Bosch +4's. ( I am upgrading for MPG/ performance) You wont need to gap the plugs just tell the parts guy your vehicle info and he'll make sure you have the right ones. I believe STL is letting you know to pick up a gap guage(half dollar sized disc with a gradient edge) to verify the plugs are gapped correctly, as sometimes they get dropped in box and can be bent to incorrect specs causing issues. other than that it is prettymuch pull and replace.

P.S. If you really need it I can snap a shot of my wires on the coil for you if you have a 4.0 motor. I have JBA wires and they come with really nice labeled collars.
Just realized your truck info is in your avitar info. So hopefully your plugs are easier to get to, and I don't know if yours has the same coil pack setup.
