What was also interesting for me is that as I never read cycling mags so as far as new innovations I'm a cyclelasaur - even some of my bikes go back to 1800's. So you have probably saved me months of having to buy these mags and I particularly liked the spoke repair kit and will add that to my touring list.
As John pointed out - mirrors are personal choice mine is a flat mirror that Velcro's to the handle bars, easy to remove for shaving, getting grit out of your eye etc.
I would be interested which of your list you would never leave home without on an extended metalled road tour.
From your list the items I would probably never make use of would be the various small bags dotted around he frame, simply because any small items kept in them could easily be accommodated in a handle bar bag and taken with you when you have to leave the bike unattended. I prefer a few small colour coded nylon bags inside the bar bag so my valuables etc are easily identified.
