Recieved many answers, thanks to Dan Anderson for the answer and Explanation:

lose these 2:
domianname IN A
www.domainname IN A

Replace with:
@ IN A xxx.xxx.xxx.xxx

In the db files the @ sign represents the domain as defined in the
named.boot/conf file, and any entry in the db file on the left that is not
followed by a period the @ is added by bind. (Most likely the example
which gave you this idea was for 1 server that handled numerous subdomains
like ucb.edu (as the domain in the named.boot/conf), the first one would
define a host domainname.ucb.edu and the second would define another as
www.domainname.ucb.edu)

Thus....

domainname would become domainname.domainname.com
www.domainname would become www.domainname.domainname.com

The way your files seem to be setup you really just need:

@ IN A xxx.xxx.xxx.xxx (The @ is just expanded to
domainname.com)
www IN A xxx.xxx.xxx.xxx (since there is no period after www
(www.) the @ is appended to be www.domainname.com)

As well as appropriate MX records.

The O'Reilly book is really indespensible.
