I don't use a forwarders, and just fill the root.hints with the output 
from dig, that way you don't rely on a specific ISP.

Here's my named.conf; NOTE I do dynamic updates from my DHCP server,
so I serve for 127.0.0, and 192.168.0, both forward and reverse.
Of course you need to setup the zone files too, at least for the
static addresses.

options {
	pid-file "/var/run/named/named.pid";
   directory "/var/named";
   auth-nxdomain yes;
   // query-source address * port 53;
};

zone "." {
   type hint;
   file "root.hints";
};

zone "localdomain" {
   type master;
   file "zone/db.localdomain";
   allow-update { localhost; };
};

zone "moyville.ie" {
   type master;
   file "zone/db.moyville.ie";
   allow-update { localhost; };
};

zone "0.0.127.in-addr.arpa" {
   type master;
   file "zone/db.127.0.0";
   allow-update { localhost; };
};

zone "0.168.192.in-addr.arpa" {
   type master;
   file "zone/db.192.168.0";
   allow-update { localhost; };
};
