If the cleat is in the centre of the ball of your foot, then that's where the people at the LBS's were telling me - they were telling me to get off my arches. Or am I completely confused? Veterans, can ya help?
The cleat should be positioned very slightly behind the centre of the ball of the foot (9mm is less than 1/2 inch), so that the back half of the ball of your foot is taking most of the pressure.

Also, sore knees are not good - your knees should not hurt after riding. I guess if you have been pedalling on your arches, that could be the cause of the problem, other possibilities are - your seat position is wrong, or you are pedalling in too high a gear (mashing).

First thing to do is get your foot position right on the pedals, then if the knee pain is still there, look at other parameters.

The tail bone pain has me a bit puzzled .... have you had a previous injury to your tailbone?
