Your first part indicates says status: SERVFAIL so you might want to recheck the /etc/named.conf for starters. Also, it's pretty handy to use the webmin tool for setting up dns and dhcp.

Here's what mine looks like.

i think it's ok to not get an answer section when querying localhost. my bind9 doesn't give me one.
why would you need it?
