Well, I can help with finding out what is running: The services should show up in a menu (like) System > Administration > Services But most *nix admins learn that the commmand line is often more explicit and/or versatile than the gui interface. It takes some getting used to, though if you are coming from a Windows environment. For example, on a RedHat-like system, you can run (in a terminal) /sbin/chkconfig --list or /sbin/chkconfig -- list | grep "on" or /sbin/chkconfig -- list | grep "on" > /tmp/onlist and then you can maybe print out /tmp/onlist I am not a real sys admin, but I think most of them-good-guys will tell you that you really should know or find out "what and why" for every service that is "on". If you are new to *nix admin, you could start by asking for suggestions on references -- although "google knows everything" can often be a good strategy. And don't be shy about asking for help. I would suggest starting a new subject line for separate question topics, so that the archive threads will naturally collect the pertinent commentary.
