My solution to this was to create two TransformGroups that were the roots of my "world" objects. The topmost TransformGroup I used for each of the mouse behaviors to (zoom, rotate, translate) operate on. The TransformGroup below this I used as the pivot point of my mouse rotation. In other words, this TransformGroup translates the object you want to rotate back to the origin and the parent TransformGroup rotates it. I hope that makes sense.
