It all depends on how thick you put your filler on. If it was put on real carefully with skill there's very little to sand so you can jump straight to the fine grit. If not, start with the coarse or you'll be there sanding forever.
What about between coats when priming/painting?
I tend to follow the instructions. For something like a clear polyurethane I absolutely sand very lightly with something like 400 grit. For a latex paint, no. FWIW, I think it would be too soft to sand unless you really let it fully dry.
For those of you who've used Duratex, are you sanding at all between coats?
Once you use Duratex you'll understand that this is a virtually impossible proposition unless you have a paint curing oven. Even when it's dry to the touch ready for the texture coat it's still pretty soft until it has cured. There's no way you could sand it IMHO between coats unless you were waiting for it to fully cure.
