1) Unfortunately, no, there is no way to write all of the annotations to the files at once as this is not something I want most users doing anyways. Until I can properly support editing embedded PDF annotations in MobileSheetsPro, I don't want users saving out their annotations and then finding they can't edit them later.

2) Yes, each .msb backup file contains all song files, so if you restored an older backup, it would restore the original PDFs.
