You're going to give up on Nagios after three days? You're gonna have to devote more time to learning this than that. Nagios can be a powerful aid, but it's nothing you're going to get the hang of overnight, and it looks like that's what you're expecting. I've been using Nagios for three months already and there's so much I don't know. It took me about two weeks to really get it generally working the way I wanted it to.
I would seriously recommend you stick with it a while longer. The time investment is well worth it.
Anywhos, most of Nagios is conveniently located inside /usr/local/nagios. If you're dead-set on removing Naigos, then running these commands should get rid of most of it...
rmdir --ignore-fail-on-non-empty /usr/local/nagios (I assume here, of course, that your system's rmdir command will work with that option)
Then you'll need to go into your httpd.conf file (assuming you tried to get things set up for the web interface) and remove the lines concerning the ScriptAlias for your CGI's and the Alias for your /usr/local/nagios/share directory.
