I used to have both of these problems and a good bike fit solved it. Perhaps you could revisit the LBS where you had the fitting and explain the issues and see if they can adjust your position. If they are any good they should be able to.

Other have also made good suggestions about the hands.

Re the feet - for me - moving the cleats back so that the spindle of the pedal was slightly behind the ball of the foot worked a treat. And the LBS said that's what they usually try for the numb foot problem.
