I hate to be the one to state the obvious, but in order to freeze people you need to speed up the shutter. If you speed up the shutter you need to either increase the ISO or open up the lens. ISO 400 does not leave a whole lot of room to work with.
Blurry people in a pano is very noticeable, no matter how subtle, and not acceptable, especially for a paying gig. Sometimes you just cannot avoid blurry people. It is all up to what the customer is willing to accept.
If you are going to be doing commercial work, you need the right tools for the job.
I shoot plays in very low light situations. Before I obtained professional grade cameras I struggled to get good clean pictures. Once I got my Nikon D3s, my job got much easier. I have pictures that are totally acceptable at ISO 56,000. I use 25,600 all day long. I can shoot at 1/500 in low light situations because of the high iso performance. I can focus more on getting the shot rather than worrying about noise.
I hope you are shooting RAW.
Spend some money and get a camera body that performs in low light situations. The job of shooting a pano in low light with moving people will be much easier. Heck you could get a very good used Nikon D3 for under $1500 now. The D3s is fast approaching $2000. Even a D800 is almost affordable now. I am sure you can pick up a similar used Canon if that is your preferred camera. Pro bodies from 5 years ago still perform great and coming down in price every day.
Get the right tool for the job. It makes the job much easier.

People are not moving much because I took several shots at each position, then masked out movement.
