Generally speaking, no. There is a very very very ... very small effect, called "frame-dragging", also known as the Lense-Thirring effect. This is less than 0.0018 degrees per year.

Since the gravitational field is not bipolar, like the north and south of a magnet, there is no such thing as the field being in motion as the Earth rotates..but then again, gravitational anamolies follow the rotation of the Earth so, on second thought, I would have to say yes.

Gravity is proportion to mass. Mass can vary due to different density material (e.g. granite rather than sandstone rock). In such cases, I'd answer that YES the gravitational anomaly rotates.
Gravity is also inversely proportional to distance. Where density is constant, and there is a variation in the shape of the planet, the gravitational variation could be attributed to a change in distance, between the subject & the earth, rather than a change in mass. In that case, the gravitational anomoly might be said NOT to move.

Hi. No. The field affects space around it but is not like spokes on a wheel. If this were not true then at a certain distance from Earth the rotating field would travel at the speed of light.

Two minor components of a spinning body's gravitational field *DO* spin according to General Relativity. The Newtonian field is not affected by spin.
