1) The option domain-name-servers should be defined in the subnet block
2) Unless you are running DNS on your default gateway machine, I believe 
that you need to have a different DNS server.

My dhcpd.conf looks like this:

subnet 192.168.0.0 netmask 255.255.255.0 {
  option routers 192.168.0.1;
  max-lease-time 604800;
  default-lease-time 604800;
  range 192.168.0.20 192.168.0.30;
  option domain-name-servers xxx.xxx.xxx.xxx, xxx.xxx.xxx.xxx;
}

Where the xxx.xxx.xxx.xxx are replaced with the correct DNS addresses.

HTH..
