SECOND QUESTION

רבי חנינא stated that if he did the ketores before the shechita of the par, he must do the ketores over again. I was wondering as to when would the kohen gadol enter the Kodesh Hakodoshim in order to remove the first kaf and machta that he placed there? Does he do that when he realizes that he must do the ketores again? Perhaps, he goes in with a different kaf and machta and on his way out, he removes the first set? Is there enough room between the poles of the Aron to have the first kaf and machta with the ketores and now have a second?
