Should there be an A-record pointing to my nameserver?

Well - this is just me but I have glue records for my machines in the
'se' zone and NIC-SE requires the same glue and NS records to be
present in the zone I am serving. Which caused me a great deal of
trouble at one point in time (changing name server IPs was hard to
coordinate properly, plus I didn't have the time to actually
coordinate anything either), but it seems like a good practice.

Remember that answers with an authority section mentioning a "lower
level" zone are generally preferred; so if you are authorative for
foo.bar, the root servers have a glue record ns1.foo.bar but you do
not, most people will probably get NXDOMAIN when looking up
ns1.foo.bar. Especially if your negative TTL is high.
