And I guess the other piece of this would be finding individual packages that are not encompassed by the groups - or pulled in by dependencies. Is there some database-like approach to take the full list of packages, then reduce it to the minimal list of groups and top-level packages to pull the rest in? It probably will work to hand the raw list to yum but I'd like to make an understandable list in a script even if the packages had been added piecemeal in the first place as someone noticed the need for them.

The command 'package-cleanup --leaves --all' (from yum-utils) will help you. Leaf packages are those which are not relied upon by other packages.
