Harry Potter and the Order of the Phoenix Literary elements and foreshadowing (warning spoilers)

I have really enjoyed this chance to go back through the books. I have been reading them this time knowing the end and looking for the clues J.K. Rowling left for us. The fun and quite obvious one in this book was the whole chapter "In the Hog's Head" When Harry, Hermione and Ron enter the tiny pub Harry is tickled by the faint odor of .....goats. In one of the other books and (I can't remember which and don't want to be troubled with looking it up since no one reads this blog anyway) Albus Dumbledore refers to the fact we shouldn't worry what people write about us in the paper. His brother is a good example he was ridiculed in the paper for practicing unnatural charms on a goat. Harry also notices the long full hair, and eyebrows and a face that looks oddly familiar. Noteably absent is any reference to his eye color which would have possibly made the clues too obvious when Harry starts seeing snippets of blue in book 7. Well we find out in book 7 that it is Albus' brother Aberforth that is the bartender at the Hog's Head. This also casts a different light on why Albus would have visited the Hog's Head occasionally and a possible explanation as to how Albus was able to know so many of the details of the D.A. without having attended the meeting. I know that Mundungus was their too, but although Albus and Aberforth weren't close they were definitely allies. Again I am amazed at how well J.K. Rowiling set up future events and how well she planned things through the whole series. It could be serendipitous or an offhand comment she made about Dumbledore's goat loving brother growing into the goaty smelling bar, but for it all to fits so nicely certainly looks like really good planning on the part of the author.
