Your weight is just the NET force on you due to gravity. If you could get into the right position in the centre of the earth (and not burn to death :p ) you would indeed be weightless, since the parts of the earth of each side of you contribute equally and oppositely to the force acting on you.
Of course this neglects the gravitational attractions of everything else in the universe, but Newtonian gravity is an inverse square law, so those contributions are negligible
