Hi, I have been struggling with exactly the same questions in some work I am doing, and seem to have hit on this same three graph solution. I am glad to see someone else is thinking this way, because rookie that I am, I wasn't sure if I was going down a bad path or not.

I did not find this a rookie question at all. This seems to get to the heart of some of the real difficult issues in Semantic Web. My perspective is different from yours, and a resource description that I author is a description of the resource from my perspective; a resource description that you author is a description from your perspective. If I have some detailed application that depends in some subtle way on my description, I may want to ignore your version; on the other hand, a third party might want to use both of our points of view. One way of tacking this problem is to have three graphs for this case: Gj, Gu, G= Gj contains triples describing my point of view Gu contains triples describing your point of view G= contains the owl:sameAs triples Then, in some application contexts, we use Gj, sometimes Gu, and sometimes all three.
