What a pain in the arse that was. Took me roughly 5 hours from start to finish 
I used this thread to go by, which was very helpful

Only dropped one item down into the darkness below, which was one of those clips that fit over 2 coil packs. Luckily when I jacked the car off the ground, it was sticking out by the suspension...so I didn't have to remove the belly pan.
Best part of the whole job was I scored a new set of the NGK iridium 4294's from Amazon.com for $4.60 each

Nothing really noticeable...if anything, a littler smoother idle, and crisper throttle response. That's about it really. The car has 64k miles on it....and I'm not a believer of 100k mile plugs, so it was time to replace them, if not overdue....all though the originals still looked pretty good.
