Don't drink the stuff, but thanks. Everyone pitches in, but a lot of people are gone for vacation, so you get me. I don't vacation. ;-)
What you are looking for, which you did finally explain well, can be found at http://codex.wordpress.org/Plugins/Navigation or in the http://www.wp-plugins.net under breadcrumbs or navigation.
The problem I had with these is that they list the post title, by default, and unless they were updated per frequent request. They only work on posts (not categories pages).
Have you taken time to go through the various Lessons and how to steps in the Codex? You'll find a lot of neat ways of doing things in there. We're adding to it all the time.
