Assuming that you weren't running offlineimap on the mailstore when it was
backed up (and thus have no local state information), offlineimap will
transfer all messages from the server to your laptop, and all messages
from your laptop to your server.
Unless you know what you're doing, retrieving your current mailstore from
your server is the safest option.
If bandwidth is really a concern, and you have access to the server, you
could run offlineimap on the server, retrieving the mail store from the
server's IMAP interface to a temporary directory, then transferring the
state information and the list of email message files and checksums from
the created maildir back to your laptop. Rename the message files in your
maildir backup as appropriate based on checksums (I'm partial to md5s
myself), cross your fingers, and run offlineimap locally.

No, but you can enable debug options to your heart's content ;)
