    A normal load average is typically 1 per CPU = 4 in your case.

    You'll find most important logs in :
    /var/log/
    /etc/httpd/logs/
    /usr/local/cpanel/logs/

    This being said, if you don't know where the logs are, maybe you should consider to get management services - at least until you're comfortable enough to manage your server by yourself ? :)

    suphp is good for a shared environment with no very active sites. Did you try to use fastcgi instead ?
    Also is it normal that azmn is running so many php processes ?

    When running suphp, top -c will show the full path of the php scripts that are running.

    When php is in cgi/suphp mode it is less efficient, so the load tends to be higher. If you change it to dso mode the load should drop, but that is less secure.

    According to your output it looks like most of the traffic is from 1 user.
