Yep, nitrates won't hurt the bacteria colonies. They'll be a non-preferred food source for any plants and algae, though, so mind the light cycle.
I'd stop dosing ammonia at this point...don't want to stress the shrimp any more than it's survived through. Your bacteria will be fine for a short while before you add fish.
I almost never change filter media completely unless it's falling apart. You can wash anything clogged in tank water or dechlorinated tap water. It just isn't a good idea to change everything all at once.
