I'm no expert, but I was messing around with something similar and made
a large, screen-sized "background" sprite that was basically the scene
with none of the "upper-layer" sprites on it.  

To move a single sprite, just blit out the existing sprite on the screen
with that particular rectangle from the backgound sprite, which leaves
you an unmolested scene with which to re-blit the new sprite.

Its entirely possible there are better ways, but it worked...:)
