The magnetic pole shift and the "wobble" are not related. The magnetic pole is known to have reversed polarity dozens of times in the past. There is no evidence that it has caused any great harm to the Earth or the life on it. The only effect is the reversal of direction that a compass will point.
The "wobble" is properly called precession, and this is a 14,000 year cycle of the Earth's spin axis revolving around like a top. This too is not any reason for concern...the primary noticable effect is the shifting of the position of the north star (and the entire sky).

Throughout Earth's history, the magnetic poles have switched numerous times. Earth "wobble" is a different matter - I forget the technical term, but as the Earth rotates, an imaginary straight line through the poles will form a circle (over thousands of years).

I know that the wobble is being caused by the spin of the Earth. At about 2800 BC, the north pole used to point at the star Thuban, not Polaris as it does today. This is proof of the wobble. The Earth doesn't exactly change poles, but both of them point to a different direction because of the wobble.

Earth is changing it's magnetic poles, not it's geographic poles.
