I don't know much about deconvolution. My thinking is that the lens distortion parameters are best obtained from many other images shot with the same focal length with the same lens. It would be hard to calculate distortion from a motion blurred image due to the loss of precision of control points.
Have you reached the stage of determining if the de-blurring works better on original or distortion corrected images? I would guess that distortion corrected images would produce better results because as a lens moves, the distortion would cause features to move at different velocities (=distances) at different regions of the image.
