No, the library sync does not currently sync settings. That's an option I plan to add. You can manually export the settings under Settings->Backup and Restore->Export Settings and then import that .mcf on the other device if needed. As far as your second question, what exactly do you mean by tabbing? Like hitting tab to cycle through fields? Why would you not be able to do that without a touch screen? If you mean switching between tabs, you'd have to use a mouse.
