Basically all i used for tools was a 1/4 drive ratchet with a 6" and 3" extension and a 10mm socket to unbolt the coils.
For the plugs i used a 3/8 drive ratchet with a 6" and 3" extension again and a very thinwall socket.
If all you have is a standard sized plug socket,you'll probably have to grind it down some.
I haven't priced out the wires,but if they aren't too bad price wise it's probably wise to spring for them.
That way you don't have to be too careful with the old ones.
I'm anal about using factory parts ,but you don't have to,so if Napa or somebody sells a comparable set,i don't see anything wrong with using their wires
They are a bit of a bear to get a good grip on to remove from the plug.
The bottom plug wires gave me more static then anything else,as my truck only has 9,000 miles on it,so i wanted to re-use my wires,and by the time i had them off,i had learned some new words and leaked a bit of blood,
It's much easier to do the passenger side if you totally remove the airbox.
I left my AirRaid CAI in place and worked around it,but it was a royal PIA.
Make sure you put a little anti-seize on the plug threads,and as Sean pointed out use some Di-electric grease on the boots and the body of the spark plug itself.
The bottom boots have a rubber insulating ring about 1/2 way down their body,you'll want a little grease on that ring too
I also greased the boots that go to the coils too,and put a little anti-seize on the threads of the coil hold down bolts
I had to use a small thin screwdriver to push down the internal tabs after sliding the red locking tab rearward to release the wire harness's to the coils
Make sure you don't eat before hand,as you'll be doing alot of this laying on your stomach across the top of the radiator,ps: the alternator makes a good elbow rest
They aren't that bad,but take your time and probably allow yourself the better part of an afternoon for the job.
I pulled my plugs to check their gaps for 2 reasons,one to satisfy my curiousity,and the second is the trucks going back on the dyno this Friday to see what we can squeek out of a 4.7,lol
