And from the acceleration chart I can see that I got sidetracked and that acceleration will be increased with increasing rear wheel torque even though that rear wheel torque will average higher when shifting either side of the power peak of the engine. Not the torque peak of the engine.

I hadn't gotten to that question, but yes, if the horsepower is "flat", then acceleration will be the same regardless of which gear you are in.
That said, it is quite unusual to have a flat horsepower curve for a large enough rpm range to span multiple gears at the same speed.
