Im not to sure but I was thinking, to scroll couldnt you just make a RECT the same size as the screen either 800x600 or whatever and then move the rectangle along your tile maps? And have your first layer of tiles already layed and blit the other layers of tiles only when they are being displayed. Would this work?

Yes it would. However, it would probably be more memory efficient if you just store the layers in RAM, and render the layers to your map surface everytime you draw. Then you would just use your viewport rectangle to figure out which tiles to render on the map surface.
