You need to apply a smoothing group/s Edit Which you can find either via the "smooth" modifier, or in face/element mode of edit poly it will be in the main rollout.
changing all the smoothing groups to '1' basically should reset them. But you can also use the edit normal modifier (see below) try the edit normals modifier

Are you sure you are using editable poly instead of editable mesh? And as for double sided face you need to make sure your Backface Cull is checked in Object properties.
What if put Edit Poly - Detach, then when you want all the things attach back together just delete the Edit Poly modifier from the "main" object.. _Revel
