Yes, but it does, more or less, EVERY year. During the course of the year, the Earth moves 360 degrees around the Sun, and at one point it does, sort-of, "line up" with the Sun and the center of the Milky Way, which is in Sagittarius.
It would be HIGHLY unlikely. The most probable event to take place in 2012 would be "Nothing unusual".
Nope, Earth lies far, far away from the center of the galaxy, on a spiral arm actually failry close to the outside limits of the galaxy.
The Earth's axis has always been tilted.
The tilt of the earths axis is constant throughout the year at about 23.5 degrees
Mars has a very similar angle of axial tilt to Earth.

No. Earth's magnetic field does not affect its axis of rotation.
Earth's axial tilt is 23.44°.
