Answer 1

The mouse position obtained from the GetState() is always according to the Windows in which you game is rendered. It is never relative to your camera.

If I understand your logic correctly, you simply need to substract the x and y position of the camera to the mouse position your obtain from the GetState().

This way, you will link your "world" position to the camera position.
