I *think* accel makes a complete kit? Just make sure you get brass terminals on the cap.
8mm plug wires, of good, or better quality, and run them per the TSB in the faq section here. I am running AC Delco spark plugs, simply because I like them better than any of the other offerings, and I simply will NOT install champions..... (I really dislike them.) PCV from the dealer... they actually have the correct flow rate.
CAI really isn't going to do you any good. If you haven't spent the money yet, don't. Just get a re-usable (k&n, spectre, whatever) drop-in filter, and call it good. The CAI system draw air from the EXACT same place the stock system does, so, the only performance improvement you get is from your wallet being lighter.
Trans service isn't too bad, just messy without the drain plug.
(and installing one is a REALLY good idea.) Have a bag of cheap cat litter handy as well. Works great as floor dry. Do not overtorque the pan bolts. You will get a leak. Specs for all that are in the service manual, which you can download for free from here
