Alrighty! Thought I'd follow this up with some photos and feedback.
Short version is that everything worked great, the Prolink was a total blast to tour on. It does make alarming noises in stop and go traffic in 95-degree temps, happily for me Dave was there to say "they all do that" and I got in the habit of shutting the bike off and paddle-footing it where I could in traffic to mitigate the heat build-up. Here's how the GPS mounting stuff worked out:
I bought and used this, in that disused mirror mounting hole on the left grip. That's a 1" RAM ball with a 10 x 1.25 thread. Looks great, works great.

I despise glass fuses and replace them whenever I can, and lucky for me a gent named Peter Smick cooked up two versions of this, one for the twin-shock CBX and this one here for the Prolink. If you look closely you'll see a spare 15-amp accessory fuse, that takes advantage of an unused spade in the connector to the wiring harness. So we have fused power to tap, bueno! Reach Peter at
pgsmick@psconsultations.com if you want one. His stuff is excellent, plug and play in this case.

We made up a short harness (with a disconnect to keep future fairing removal simple), from the accessory lead with a ground, and we wired that up to these. That's a Powerlet socket at right and a two-outlet USB to the left. Yes we drilled the fairing with a Unibit.

I used the USB to keep my phone charged in my tankbag, and the powerlet was used to power the Garmin Zumo that was installed on a short RAM arm onto the ball.

It all worked perfectly! Was also nice to be able to remove it from the bike in 30 seconds.
