The layup sounds ok, except, where on earth are you going to get 2oz carbon? The lightest I've ever seen was 2.4oz. Are your carbon spar caps going to be inset into the balsa sandwich, or lay on the inside? You will also need a shear web ahead of the aileron hinge to close out the opening in the fixed portion of the wing.
I don't know about the torque rods, except to say that having holes in the mold where you poke the wires would be a big source of problems. The holes would constantly will with epoxy. You would probably need to have dummy wires to plug the holes while you lay up the wing skins. Remove the plugs and install the torque rods before joining the upper and lower skins. Then you have the problem of demolding the wing with the torque rods sticking into the mold. Obviously this needs more thought. The thought of using wheel collars scares the begeebers out of me. Sorry for my rambling... it's late.
