"Surprised to see the recommendation of super-fine steel wool for the fingerboard, though. "
That plus some lemon oil or something similar been around for as long as I can remember re ebony/rosewood guitar fretboards. If you haven't done it, you will be surprised how it will enhance the look and feel of a fretboard that has been in use for a while. I do it maybe once a year though not with any precise schedule.
I also have always done the same with the neck because I find that for me the neck plays much easier with a dull finish than a glossy one. Normally the neck first gets glossy in the 2nd/3rd fret area from normal playing. If you fret, say, an E-shape chord high on the fretboard and slide down to 1st/ 2nd fret, you can feel your hand "grab" as it hits the gloss. Since acquiring a Taylor and reading some of their info, I see that they suggest periodic use of fine sand paper to cut that gloss. I've been doing that for many years but the Taylor recommendations are the first time I had actually heard/read such a suggestion from a guitar maker.
I have a gigging friend that probably sands his guitar's neck every few weeks. I can usually go a couple of months.
