As the shot you have isn't a full 360, by stretching it across 360 degrees of a sphere you will distort the image. Hence everything else doesn't really matter. You will have a distorted image. Reformat it so it's 2:1 (360 degrees horizontal to only half, 180 degrees vertically), the treat it till you're happy with the look as it appears through a camera on a sphere.
