Regarding the walkabout, I agree with everyone here (almost everyone) that it showed Catherine in a good light rather than bad. That it was awkward was very apparent to everyone, but both she and William did the right thing by inviting the Sussex's to join them. Given the subsequent release of his book and their documentary, I think it for the best that their presence at royal events be kept very low-key. Personally, I don't think their "second place" ranking was as big an issue for Meghan, at least, because her focus was and will naturally be attaining "top rank" in American society.
