Trees, Shrubs and Conifers: Crape Myrtle rejuvenation, 4 by pirl

Once upon a time we had a lovely Crape Myrtle (#1) in the garden but the storm, Irene, destroyed our Acer Negundo, which lost limbs that fell on it. (#2)

#3 shows how it looked afterward with suckers (since removed) at least showing us it was still alive.

#4 shows how it looks currently.

#5 another current photo to show branch structure.

Should I prune out more branches? How far up do I go?

Using the last photo as a guide, the limb on the right concerns me the most. Any advice would be appreciated. The side shoots that rise up seem to crowd the center. Do I remove them or not? Or do I remove them one at a time, stand back, judge, then either stop or remove more?

Thank you for any help you can provide.
