Hi Bahne,
I did not get the screenshots in your reply. Could you please send it out as an attachment? I can take a look and answer your questions.
When it comes to number 3. Ccomp2 was used mainly to add a higher frequency pole to get rid of any noise. This is not always required especially if you have a good gain margin with a nice layout. However, adding Ccomp2 can add a margin of safety.
