I was able to get Superuser access through the SuperOneClick 1.9.5 app from CLShortFuse (thanks for this awesome app).
Very easy process: be sure you're currently using the latest ADB composite interface drivers by Google (Android SDK).

Sweet as a nut.
I didn't use the google drivers. When I put phone in debug mode Windows 7 fired up the LG updater and all I had to do was select LG-P920 from the list.
10 seconds later... ROOT.
Happy bunny now.
