MoJo - I think part of the reason this experience with MS has been so frustrating is that usually they've been fantastic. I haven't used support much, but back when the Xbox 360 had problems, they sent me a new one right away without much hassle. My SP3 power cord started fraying, I walked in the store and they replaced without a single question. Then, for the only piece of electronics I've ever bought an extended warranty on in my life, they're being really difficult. Doesn't help that the MS store employee I had to deal with was terrible, too.
Anyway, to a more productive topic :) I tried working with online support last night, and their first recommendation was to factory reset the thing. Considering how long it takes to re-apply all the firmware updates, security patches, etc, I wasn't too interested. But there was one thing I hadn't done that gernerttl recommended - delete existing Bluetooth pairings. The pairing with my pen had been deleted, but not my mouse. So I enabled Bluetooth, saw the phantom touches, then went and deleted my mouse pairing but left Bluetooth on. Touches disappeared. Re-paired my mouse, and so far haven't seen the touches again, all is good.
So it looks like I may have gotten rid of them, for now with a simple solution - delete all Bluetooth pairings and re-pair.
Hope one of the MS employees on these boards notes this and gets it fed to their support group. Might save them losing another customer in the future.
