I would advise against using SSR1 w/ an Orange Pad. You may induce some marring with it because you are using an aggressive pad with a product that is very mild in abrasives. It is just going to cause more work on your part in the long run and the results would not be worth doing the extra step.
With what you have listed, I'd save the Orange pad for when you need some work and just run the SSR1 w/ the White Pad, FTG w/ the White Pad and EX-P with the Black.
