Yes

No, what IP they show is irrelevant. They are not authoritative, the
registry will take the IP from the registrar that the parent domain is
registered with.

They don't need the IP. The IP is only needed because of situations
like using a nameserver based on a .com domain name to be
authoritative for the parent domain. So, for example, if I set
ns1.userfriendly.com to be auth for userfriendly.com (which I do :),
remember the IN NS record only accepts hostnames. So when the query
is done, and it gets ns1.userfriendly.com has the place to find
userfriendly.com records, it does not know how to reach
ns1.userfriendly.com yet. So the "glue" record for
ns1.userfriendly.com in the com zone provides that info.
So essentially it is only necessary because of the possibility of
recursive lookups.
For ccTLDs where you use a com/net/org domain, the nameserver had a
way of finding the IP address for the nameserver independently, thus
they don't need to include any info about your nameserver other than
the hostname.
