100,000 Mile Tune Up?

[Wonko The Sane]

Ello everyone,

My relatively new-to-me 97 box is nearing 100k miles. I've just started getting the common CELs P0410, p1411, P1123, and P1125 (all related to Oxygen sensor out of range, or secondary air injection "signal implausible." These codes are according to my Durametric system.

I figure since it's nearly time to do the routine maintenance, I might as well do a full tune up.. I was hoping you guys can help me compile a list, as my Bentley book is about 1000 miles away at the moment (where my box is).

Here's what I'm thinking, let me know if anything is unnecessary:

Oxygen sensors (to potentially fix my CELs)
Spark Plugs/Wires (what's everyone's favorite brand?)
Serpentine/Drive belt
Air Filter
Cabin air filter
Brake Pads (the rotors seem fine for now), what brands does everyone like for street/AutoX action?
Brake fluid flush
transmission fluid replacement
clutch fluid replacement

Should I be looking at swapping out the Air/Oil Separator just as a precaution?

Off the top of my head, i can't think of anything else I hear commonly failing, please let me know anything I overlooked!

Thanks!
