Note: I don't have RH 8.0, so the directories in your system may be different. Sorry.
Default Apache configuration will work, you can just run it and see (default directory for your website: /var/www.
DNS (bind) should work with default configuration, too. But it's a good idea to write your own one, or just change the names. The main config is in /etc/named.conf (the rest should be in /var/named). Secondary DNS doen not come 'out-of-the-box', but it can be done (maybe after you have the primary one running?).
(good, with nice examples).
