since I'm stuck with only a PC, without a rotary buffer, I do have to use the orange pad with Menzerna IP if I want to get out any scratching. My theory is that the white pads are ok for scratchx (occaisinonally I use this for light water spot removal), Menzerna FP II, or 3M 39009 -- when I"m using these just to polish the finish but not to remove visible scratching.
It sounds to me like that's what you're doing, so you're ok. But definitely put in an order for a couple of orange pads -- eventually you'll need them for scratches or swirls.
