The mast rake won't change much about the main, seeing as it is attached to the mast and to the boom. The angle of the mainsheet gear will change a bit, but that will mostly affect the force applied to the mast that induces rotation. Obviously the angle of the whole sail will change.

The sheeting angle will change for both the jib and the spin. The jib you can adjust, the spin sheeting point and halyard point is fixed (haven't a spin that doesn't hoisted all the way to the bale). You can play with things to get the luff tension right (more pole bend usually), but because the halyard bale will move relative to the sheet block, the sheeting angle will change.
