Number of hands on the steering wheel has nothing to do with reaction time.

  No, but it determines how well you can steer. Especially in sharp turns you usually have to shift down/up. If there's an obstacle (perhaps a person), both hands on the wheel will give you more room to steer in both directions. You'll be much more limited with one hand.

    You don't shift up/down in turns, but before and in the exit path out of them.

      I (and many others) do. After a traffic light on a large intersection you will have to (or at least should) shift to second gear with most cars before you're clear of the intersection.

    It really depends on how you one-hand: arms locked at 12 o'clock, leaning toward the center is a terrible position, but left hand at 9/right hand at 3 (for RHD cars) is perfectly fine for steering response.
