Just did this today.. my first time, took about two hours total. Didn't break anything!
Picked up a set of 8 plugs on eBay for $67 shipped. I used the CAT-5 network cable method on the two closest to the firewall which worked well. I did loosen the coolant tank to provide a bit more room to slide off the spark plug cover on the passenger side.
7 of them were a piece of cake.. but that last one on the passenger's side.. I think I invented a few new curse words on that one.. the hardest part was getting a torque wrench back there - just have a few various sizes of 3/8" extensions and you'll be fine.
This was definitely a necessity:
