Clark...you've got this. Trust me. What you aren't realizing about your fellow clubbers is that the majority are not mechanics with a zeal for pc'*. Most are people like you (they start talking about it when they gather and it gets late..trust me.)

The list you posted from the dealer. It'* funny. They don't do much at all, except check things a couple times. They inspect the belts and visually inspect them. You've already done this.. lift the hood and look for cracks in the belt. Done. Wow..that'* not too bad now is it?

Start off with the basics.
Plugs
Wires

Remove one at a time and replace one at a time. Match up the length of the wire with the old one and presto. There'* no doubts it'll take a little longer the first time than the second and so forth. Give yourself a day to do the plugs and wires, then relax afterwards. You'll have plenty of daylight.

O2 sensor is a good tune up item never listed. Rach is saying she'* done it, heck..she pulled a strut off her car this past weekend. It'* easy... just ask the questions.

Besides, if you really miss the experience of going to a dealer, just follow these simple instructions:

1) Tell yourself that unless you get (insert random really expensive service of your choice here) done, your engine/transmission/car will DIE!

2) Realize that the above is BS, and respectfully reply that a tuneup will do just fine for today, thanks.
