Yes to all of above.
So you would add the host using FQDN and then follow the workaround to 
make sure gluster communicates using storage network.

Whenever you add a new host, the host is added to the gluster trusted 
pool, by invoking "gluster peer probe <host address provided>"
So, if FQDN is used and the ipaddress mappings are setup appropriately, 
then gluster communication will continue on the private network.
