I got it to work!
Select the shoulder, elbow, and wrist, then the offset group of the control and point constraint. Then select the elbow and the offset group and aim constraint. Delete the constraints and move the group out. Select the control and the IKH and apply a pole vector constraint.

I have all of the scripts used in rigging saved in my notepad. I would really like to learn more and start writing my own scripts. I think I'll probably buy Josh Sobel's latest tutorial series about scripting.
I finished smoothing weights over the weekend. Today I finished the body rig; adding stretchy arms and legs. I decided not to do IK spine. I did it and took it out. It's not the industry standard and I never use it while animating. While I was at Pixar in January, I asked about their rigs and what the set ups are like. Mike Makarewicz said that Pixar and Disney don't use IK spine generally, the option is there but it's not used. It's not how a spine anatomically functions, so why bother?

Smoothing weights takes forever. I don't know how long this one took, but it was too long. I had to reposition the clavicle and spent too much time getting that to be close to perfect. I really do love this model, the belly rolls were a lot of fun to get "right."
