Any chance work will issue you with a Mac? This would be so much easier if they would. You'd be able to use the iPad as an external display for the Mac, and could run Mac note taking apps (which save all their data on the Mac) on the iPad screen, with full touchscreen and pencil support for drawing/etc. The iPad basically becomes a Cintiq.
I think the only way Windows can connect to an iPad over USB is with "iTunes File Sharing" which requires installing iTunes on Windows - then it will be able to access some data on the iPad. It used to be pretty widespread for note taking apps to support that, but I'm not sure how common it is these days. Almost everyone uses cloud sync these days.
