Both problems stemmed from the fact that Apple has not updated the bootcamp driver package to support Windows 10 yet. So I ended up wiping Windows 10, installing Windows 8.1, which is supported by bootcamp, and then immediately upgrading to Windows 10. Now I have a better video driver and right-click is working. So a little extra time spent but a working system. And Win 10 seems to really like the MBP hardware as it's very quick and responsive.
