I can't uninstall parallels 6 from Mac?

When I get to the 2nd uninstall step, it says that I have to close parallels explorer and parallels mounter first, but I can't seem to find their location in order to close them. Is there a way to shut down all programs, closing parallels explorer and mounter? Or is there a "task manager" type system for Mac's that can view and stop/close processes? Please help!
