No one can really answer that until they begin to practice/play. I think Moore will blend in nicely, as he is a high energy guy and knows his role will be to rebound, play post D and hit an ocassional mid-range jump shot.
Marbury has never been a bench player, and will need time to shake off the rust from not having played in over a year. Doc, KG, Ray and PP will have to keep the reigns pulled tight on him would be my guess.
