Hi,
here are the answers to your questions:
1. The manual has been updated last month. You can find it here: http://www.zubersoft.com/mobilesheets/manual.html
2. To use the companion app, it has to be connected to the tablet. There is no way to use it to prepare your sheets.
3. MS will read PDF-files just fine. It's also capable of reading picture-files, but you don't have to convert all your music that you have now.
