So are you certain BIS is setup to use OWA and not IMAP? I'm a bit confused by your post.

Seems to me like you should have a backup of whatever you're working on so if a device wipe is necessary it's not a big deal. The backup utility in Desktop Manager is very handy.
Yes, you can delete just the service books.
