DNS is killing me ! (need another set of eyes)

Ok, I made the jump and formatted my win2k box and installed redhat 9.
Now im having a bear of a time getting my DNS set up.  I have perused a 
gazillion how-to guides and am obviously missing something :(  Im hoping 
some kind soul can help to keep me from going back to the dark side :P

Basially, I would love another set of eyes to look at my config to see 
what I am doing wrong.

Background Info: I used to have my web server, application server, dns, 
sendmail and DB on my windows server and it all worked last week, so I 
know the problem is not in my router or my domain itself...

Also, I shut my firewall completely off for this test so I know it must 
be my DNS config.  (my router is only granting access to port 80 for 
web, 53 for DNS and 22 for SSH)

Finally, I believe DNS is up and running because I can telnet to 
localhost 53 and when I grep for "named", I get:

[root at jomamma root]# ps -ef | grep named
named     5468     1  0 18:47 ?        00:00:01 [named]
root      5649  5622  0 22:13 pts/1    00:00:00 grep named

I will list my configuration below for convenience...   I will be so 
happy if anyone can point out ways to perfect my setup.

Thanks !

For these examples:
1.  I am changing my domain to "mydomain"
2.  The internal ip address of the linux box is 192.168.1.11.
3.  The name servers are ns1.mydomain.com and ns2.mydomain.com and are 
are registered with my server as their ip address (listed as 
100.100.100.100 below).  This ip is the external address of my linksys 
router which is forwarding port 53 to my server's internal ip.
4.  admin email is admin at mydomain.com
5.  server name is jomamma
