instead of services use /etc/init.d/<service> <action> (ie /etc/init.d/sshd start), going from Fedora 6 to 13 sounds like a heck of a jump, I wouldn't really even want to consider how badly out of sync some things may have gone... however you could use find or locate to find some things... if yum still works try downloading locate, it should install two commands, locate and updatedb (will need root privs to run updatedb). updatedb will make a database of all the files you have to help locate things a bit faster then manually doing finds for everything.
I think re-installation might be one of the options I would offer up, to fedora 13. Just back up all your important data first if you decide this path might be better for you...
