How does the Canon handle at 3200? I typically shoot with the white balance at incandescent. Set the meter for spot. I've found that a center isle seat about 8-10 rows back works very well for my 28-70/2.8 and 70-200/2.8i VR. Can you add the high speed noise reduction after the fact since you are shooting RAW, if not and there is such a thing in camera, i would suggest giving it a try ahead of time.

Good Luck with it.
