First, about using FC-1 and FC-3 bind. Those Fedoras aren't supported 
now so it doesn't contains security fixes etc. It's strongly recomended 
use Fedora 6 at least (or bind from there) if you want have fixes for 
all known CVEs.

Those upper 2 files isn't named config files. It's for named + D-BUS and 
logwatch + named cooperation.

You could use what you want :) 
/usr/share/system-config-bind/profiles/default/named.conf is used by 
system-config-bind (GUI utility for creating named's configuration) to 
generate default /etc/named.conf. 
/usr/share/doc/bind-9.3.4/sample/etc/named.conf is more advanced sample 
of /etc/named.conf. Use info from those files and create your own 
/etc/named.conf
