in blender to mirror a model go in edit mode and use the mirror modifier also join all the meshes before you do this, also back up your copy of the model as well as for to retain her width go into edit mode press s + y and you should be able to stretch out her y axis, s + z is the height and s + x is her width from the front of the model.
also from the 2nd screen shot it looks like the models are skewed possible squashed too look at this page at the bottom of the 1st post and look how to fix those.
