Sure, you can run only sshd if that's what you want to do.
To figure out how to stop other unwanted services, first you need to know what those services are. Then find their startup scripts and disable them. There's probably a GUI way to do this, but I'm a command line person. The GUI way would probably be distro specific.
As root, you can run "netstat -anp | grep tcp | grep LISTEN" from the command line to get a feel of what your system is running.
