Dumbledore gave Hermoine the fairy tale book, because it was clearly the fact that he was aware that Hermione is alert, bright and can decipher things more easily than other wizards/witches. The book led to the discovery of the Deathly Hallows in a roundabout way because of the emblem on the first page, and the tale of the three brothers and Death.
The Elder Wand doesn't technically make the user all mighty and powerful, because how would the predecessors of the wand be killed or beaten in a dual? By winning in all sorts of fashions, and Dumbledore and many others stated that Albus was always one notch better than Grindelwald.
Sad that Dobby died.
J.K loves to use that word, and has a repetitive flow of using words again and again. I noticed it far too often.
