I was very interested in the fate of #12 G.P. too, especially since RAB HAS to be Regulus Black. And remember Kreacher kept a lot of those things in his little hole.
Now, do you think Dumbledore will come back? Remember, at the end, Harry thought he saw the phoenix rise from the flames on Dmbldr's tomb. I always thought that the phoenix as his pet was a bit of foreshadowing, that perhaps Dumbledore will find a way to come back. I definitely think he will find a way to communicate at least once. His picture is on the wall at Hogwarts, and Harry's parents came out of V's wand. Maybe he'll use one of those things, the picture or Snape's wand.
I also think Aunt Petunia might come into play in the next book. I think she was feeling a bit guilty after Dumbledore talked to her the last time.
