Get a headlamp. They work great, give plenty of illumination and aren't too distracting. I don't think that hooking one on your belt or waistband would be too helpful. I also don't know why you would need the maglight once you have a headlamp.
It seems to me that you are packing too much stuff unless you are planning on doing technical offroad running in the dark.
I run in the dark and don't carry anything different from daytime running except (1) a Nathan reflective vest and (2) occasionally a headlamp. Usually I let my eyes adapt to the dark if I'm familiar with my running route.
