To avoid this you can bake normal map with uniform light distribution across the whole map using for instance NVidia normal map plugin for Photoshop or 3DsMax. Also I should say that using Prefab you can get nice result too. The problem you have (baked light source on one side of the object) I noticed when using Away3D Normal map generator. In this case try to add several lights around the object.But I would suggest use other tools for normal map creation as I mentioned above because I found that the overall quality of such a map is not that good in comparison even to Prefab(Once talked about this issue to Fabrice but I am not sure it is solved).
