Approximate to a thousandth of a degree?
.
I don't know the size of the error, and of course the calculations to determine that are almost as complicated as the calculations to get an exact position for the moon. But I'd guess on the order of a few degrees.

Again, afraid not. While the new moon will have the same approximate latitude as the sun, the full moon will have approximately the opposite latitude: south of the equator if the sun is north, north of the equator if the sun is south. Other phases will have intermediate latitudes.
