If the diameter of Earth increases, the rotation of Earth will absolutely slow down. It's similar with the rotation of skater. If they stretch their arms out, the diameter of their own will be increased, therefore the speed of rotation will be reduced. The distance between Sun and Earth is determined by the mass and diameter of them, according to the law of gravity. F=GMm/d^2. The axial tile of Earth is determined by the movement and distance of moon. Earth has a very stable axial tilt resulting from the existence of our neighborhood-moon.

The diameter of the Earth relative to the gravitational pull of the sun and other planets is pretty inconsequential considering how much bigger the sun is than the Earth. What I would worry about is how the North and South poles are slowly switching places....

Hi. Assuming the same mass then only the rotational rate would change.

If it's diameter changed... but not its mass? Then it would still be the same, probably. Of course, it would now be so much less dense, we'd have a billion other problems....
