That means that the equatorial radius is getting shorter by 0.16 mm per century, while the polar radius is increasing at twice this rate.

The Earth's speed of rotation around its own axis does not affect the speed at which it is orbited around the Sun. A "year" would still be the same amount of time for us, it's just that the days would be longer and there would be less days.
