finding that I can use ISO 3200; Neatimage is miraculous at removing
noise.

CCD is about 3 times more sensitive - from memory.
I wouldn't use ISO 3200 unless that's the native gain of your camera.
A lower ISO means less noise & you won't reach the well depth as quickly.
Removing noise creates artifacts - the idea is to get a good signal to noise ratio to start with.
I would say - just get out there & try it.
