GNU tar version >= 1.27 has the required support, so I suppose if:
tar --version | grep 'GNU tar'
returns anything you can use '--xattrs' otherwise use the old command

Do not know, never tried ;-)

What is missing from the supplied script is a test to see if the samba 
daemon is running, which I think shouldn't be whilst you backup the 
directories.
