Thanks Barry, I thought about that soon after I posted.  NAT will
allow my internal server to query the root servers and my IPS's DNS
servers ... as Homer Simpson would say ... "Doh!"  :)

Ok, so I need to get my NAT configured correctly Monday 1st thing. 
Now for the finish line.  If the external server is actually using the
internal server for DNS lookups, do I still run a server on it to
advertise my www,smtp,news,ftp,etc. to the rest of the world?  As I
don't want the rest of the world to know that pc1.mydomain.com is
actually 10.10.10.200.

So what I am assuming is that on my dns.mydomain.com
/etc/resolv.conf
domain mydomain.com
nameserver 10.10.10.10 - for arguments sake

But I still have named running on dns.mydomain.com with its own view
as a primary server?  With only the external hosts defined in its
resource files?  And any change to an external host would need to be
modified on both my external server and internal server.

And let me just say thanks to all the assistance and input from
everyone who has responded so far!
