I do more event photography than I do portraiture. And I believe that my camera has only 9 AF points on it. But I manage pretty good doing fast moving, low light, event photography using my center focus point. I’ll get my focus and keep holding the shutter button halfway down and snap back to my composition I was going for. Or another way is learning to use your focus lock.
As far as color balance, 90% of the time I can get away with using auto color balance. This is probably the only setting on my camera that is set to auto.
