Not sure about the second, but I can help with the first ;-)

Find a file called 'dns_update_list' on Samba DC, open it in your
favourite editor, then find this line:

AAAA  ${HOSTNAME}                       $IP

Comment it out and close and save the file. This will stop Samba
putting the ipv6 address back.
