It might help to address the 'oversmoothing' problem first as whatever the quality of the texture this will always show through... See where all the right-angle sharp edges look messed up in Poser? That's because Poser expects nice organic curvey meshes. To fix this, either add a 'bevel' to each straight edge in Max, or 'split vertices' in UV Mapper... I take it you are using Steve Cox's UVMapper, right?
