If you want to use samba shares for the home directory, make sure you use the cifs filesystem and not smbfs. IMHO, using NFS would be better for this purpose. Using cifs, you will get permissions and acls but locking may not work right.
If the share containing the home directories is mounted on /home, then you shouldn't need to change anything. Simply mount the samba share on the /home directory.
Even if you already have users on the local /home directory, you can mount the samba home share somewhere else and use that directory instead when you create a new user.
