Something I've found very helpful when making a scene is to add a simple prop - say the Poser ball - and then in your Hierarchy window drag and drop all scene elements on the ball. Now make the ball invisible either by setting tansparency to maximum and highlight to 0 or just turning off visibility from the objects parameters. Now when you want to move your scene around it will move as one object just by manipulating the ball. You can move and rotate the ball to help you set your scene around your main character(s).
