I know your pain :-) I can't point you to a bolt on solution, but what you probably want is a tree structure of some sort. Have a read of http://www.sitepoint.com/print/hierarchical-data-database/ for the concepts; scroll down to Modified Preorder Tree Traversal. There seem to be a few nested set classes out there to manage this sort of structure, e.g. http://www.edutech.ch/contribution/nstrees/index.php or search on "nested trees".
