Actually, in 9.1, you can go through yast and see what's running. Open up yast, and go to
System >> Runlevel Editor then click on "Expert Mode". You should be able to scroll down and see if apache is running.
Assuming that you installed Apache from the Suse disk/ftp, you you shouldn't have had to do anything with the config because (if I'm not mistaken) it's already setup for general/generic usage...if you wanted to do something exotic, then you would have to mess with the httpd.conf file, but I think right out of the box, if the service is running, it should work with no setup.
PS: Don't go turning on and off stuff in the runlevel editor unless you know what exactly what it does...you could very well mess something up.
