Actually, to get in specifics, weight and mass are 2 separate things. You mass never changes as you said, but your weight does. Your weight is the pull of gravity on your body. Learned that tid bit of information in 8th grade, when they were explaining how much the metrics system ruled and how much our system sucks.

Nobody weights more or less on or in any planet, moon or other object just because you are there. Your weight is set by your mass. Jupiter is heavier than Earth and Earth is heaver than Venus. I am heavier than most people because I have a large mass (I am a Tall Fat Bustard). This being said the reason why you weight less on Luna (that's our moon) is because the scale has changed. But in the center of the earth the scale is still Earths. The pressure would be intense. Oh say, much more than being a few miles below the surface of the ocean. Of course you would be liquefied and then weight less because you would have changed your mass. Quantum Mechanics anyone?

No. Weight is defined as the nett force you excert on an object as the result of your mass being attracted by gravity. Since the gravity is equal in each direction, you would indeed weight nothing. But you would feel a pretty high pressure of an entire planet on top of you. Subtle difference between weight and mass. Another way to look at it is using the concept of minimizing the potential energy in a system (which is a tendency of all natural systems). If you exchange a certain volume of the most dense part of the core (the center) with a less dense part (the crust) that requires labour. You move something that has a high mass against the gravity which requires a lot of energy, and you move something that has a lower mass in the direction of the gravity, which will only yield a little bit of energy.
