Thanks to all.
And in particular: thanks to Chris KF7P for the reference to W8JI's document (and of course thanks to W8JI for the document! I'll be at "better but not perfect" on day 1 (hopefully by dinner time today :-)
BTW, that "optional" bonded run from tower to grounding system in the middle of the run perfectly illustrates my setup.
I hope others will find these posts in the future: I found lots of links listing and explaining the relevant parts of the NEC, but W8JI's material gives great examples of the practical implementation of that code, which is what was needed to have that info click into focus.
I'll be adding control line suppressors and a grounded and protected power strip in the coming weeks (Don't be surprised if I order from KF7P :-). I'm not in a super hurry on this next stage because I live in such a low-probability lightning area; it will be completed in the next month or two - as soon as the CC gets recharged...
Finally, if you're doing grounding I suggest a visit to http://www.kf7p.com
and in particular to http://www.kf7p.com/KF7P/Tech_Resources.html
. In honesty, everything I needed is on this list.
Even someone who's been a ham for 52 years needs "Elmering" once in a while.
