   SO let me post the zones to see if this is how to do it correctly..
   this is not currently setup, but want to make sure I am correct here...

I don't see anything wrong with the subdomain delegation.

   I DONT NEED ANY A RECORDS RIGHT?

You need A records for ns1.illicom.net and ns2.illicom.net in the
illicom.net zone file.  Otherwise, how is anyone supposed to make use of
those NS records?  The subdomain is totally irrelevant to this mistake.

Similarly, you need an A record for smtp-in.illicom.net and
smtp-out.illicom.net.

Maybe these things are in the real zone file, and you just sent an excerpt.

The only time you need special A records when delegating a subdomain is
when the nameservers for the subdomain have names in the subdomain, e.g. if
you were delegating paxton.illicom.net to ns1.paxton.illicom.net.  In this
case, you need a copy of the A record in the parent domain; this is called
a "glue record".  However, in the special case where the master server for
the parent domain is also a master or slave for the subdomain, this isn't
really necessary -- named will automatically pull it from the subdomain.
