Richard,
I don't have time to go through that config line by line but here is
mine that works. It is not perfect, has some unnecessary stuff in it,
the domain used is a private domain but like I said it works so it
must have at least as much as necessary to make it work.
------------------------------------------------------------------------------------
[bepstein@dellnikon ~]$ more /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
subnet 192.168.65.0 netmask 255.255.255.128 {
# --- default gateway
option routers 192.168.65.1;
option subnet-mask 255.255.255.128;

range 192.168.65.50 192.168.65.125;
# we want the nameserver to appear at a fixed address

Hope it helps.
