The answer to the depth question can be found in the voluminous correspondence on 'The gravity train', as you descend in a shaft the force of gravity depends only on the mass of the body below you i.e assuming no increase in density halfway to the centre of the Earth G would be about 1.1 m/s/s.
This is counter intuitive but everone agrees on it!
