Well, I've discovered the answer to my second question.
This is a new machine I built in January and I thought I had applied all the Windows Updates. Not as such. The missing one was KB967715. It creates an extra registry entry alongside the "NoDriveTypeAutoRun" one under Explorer - it's called "HonorAutorunSetting" and should have a value of 1. It fixes exactly the behaviour I had experienced where the autorun.inf is executed by Explorer on a right-click.
So be sure you have BOTH entries in your registry for Autorun/Autoplay to be effectively disabled.
