Sparkling Effect

I have an image of a waterfall going into a lake. I want to give the effect of motion. I want to have some little sparkles coming down the waterfall, and have some sparkles moving around in the lake itself. I want the sparkles to have like a reflective light effect (like alternate from a shade of blue to bright white every second or so, something like that).

Does anyone know of a tutorial for this? I am decently new to Flash MX but learning quickly. Thanks in advance.
