As long as you set your figure to "body" you should be able to use the buttons at the top of your workspace to move and rotate, although I have experienced difficulties that need Mechanismo's method. As for Bryce, feel free to visit the Bryce forum. In a scene like that where shadows and lighting is important, I prefer to bring the poser model into Bryce and manipulate it there. If you don't have it yet, look in the freestuff area and find a program called Grouper. That's a very worth while app to have if you are going to bring poser into bryce.
