Bind BIND 9.3.5 configuration

[Kevin]

I installed bind 9.3.5 on my new FreeBSD 6.3 server. I copied
named.conf directly from my old server (originally from the Internet),
it seems working fine but with some startup errors. I hope someone can
explain or tune the configuration a little bit for me, any input would
be greatly appreciated.

Q1. Bind gave me errors on the following lines due to missing files, I
have only empty.db, localhost-forward.db and localhost-reverse.db.
Should I modify all localhost.rev to localhost-reverse.db? Is it safe
to remove all lines about localhost-v6.rev?
-------------------------------------------
zone "0.0.127.IN-ADDR.ARPA" {
        type master;
        file "master/localhost.rev";
};

// RFC 3152
zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.ARPA"
{
        type master;
        file "master/localhost-v6.rev";
};

// RFC 1886 -- deprecated
zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.INT" {
        type master;
        file "master/localhost-v6.rev";
};

zone "localhost" IN {
        type master;
        file "master/localhost.rev";
        allow-update { none; };
};
---------------------------------------------------


Q2. Regarding the following lines, it seems that I should uncomment
the forwarders, is it the the same IP in /etc/resolv.conf? Or I need
to ask my ISP?
---------------------------------------------------
// If you've got a DNS server around at your upstream provider, enter
// its IP address here, and enable the line below.  This will make you
// benefit from its cache, thus reduce overall DNS traffic in the Internet.
/*
        forwarders {
                127.0.0.1;
        };
*/


Q3. About the following comments, should I enable a local name server?
and how to do it exactly? I have added 127.0.0.1 in resolv.conf, but
how to enable it in /etc/rc.conf?
------------------------------------------------------------------------------------------
// If you enable a local name server, don't forget to enter 127.0.0.1
// first in your /etc/resolv.conf so this server will be queried.
// Also, make sure to enable it in /etc/rc.conf.

I have used this configuration for several years and always quite
confused. I have put my named.conf at
http://www.msofficeforums.com/named.conf . Please give me some
suggestions. Thanks!
