texture first to insure texture streching dosn't occur.

to get them all bound to a skeleton, select all the pieces, and then bind them to the root of the skeleton.

As for the subd's, when you convert them back into polys, make sure that it is set to "Control Points", or "Verticies". Now, make a new layer, and call it highRes. Create another called lowRes. Now, bind the low poly to the skeleton, and then the subd to the skeleton. now, put the highRes into the highRes layer, and the low as the same.

Hope this helps
