NSI's WHOIS database links domains to servers by the server's handle, not
its hostname.  I'm not sure if they'll let you rename a host using the
Modify Host form, but if they do it should be reflected automatically in
all the domains that use that host.

It should be OK.

You shouldn't need to modify the domains, because the server handle hasn't
changed.

Since the IP address isn't changing, it doesn't matter what name is used to
refer to the nameserver.
