the first line of your example would be something like:
Property p = (Property) session.getItem("/foo/theTemplate/mapping:lastUpdate");
But since graffito, lenya and jackrabbit communities are interested in such a tool it would be cool to work together, that would be the apache way, right? :). AFAIK the proposal discussed in the graffito dev list deals with many of the issues you are talking but I didn't see any reference to a cache with already mapped objects.
