Hi, You don't convert degrees to quaternions directly. You convert vectors to rotations (which are quarternions), and you do that with the llEuler2Rot function.
As for the rest of your query, you might find http://wiki.secondlife.com/wiki/Rotation helpful - I don't know much about rotations, but I bet the answer you want is probably in there somewhere. I hope my reply's been helpful, even though I personally don't know much... - Sophie.
