The epilogue may have been cliched, but I'm still glad it was written in. I wanted to know that they were happy and safe.
The whole elder wand - who was the master - was confusing to me also. I think that Draco became the master of it when he disarmed Dumbledore right before Dumbledore was killed. Although Draco never picked it up or used it, he became the master. Voldemort stole it out of Dumblebore's grave, and he erroneously assumed that Snape was the master of it since Snape had killed Dumbledore. Harry disarmed Draco later, but Draco wasn't using that wand, so I'm not sure how Harry became the master of it (or was he, I'm fuzzy on that part).
Snapes memories were so heartbreaking. I really had a lot of sympathy for his character during that chapter. On the one hand, I wish Harry would have known about Snape's protection and his love for his mother while Snape was still alive. On the other hand, it makes it more poignant that he didn't know until it was too late.
On the sword, yes, he may have gotten it from the Room of Requirement. I had forgotten that comment about Neville being the master of it.
Lizziness, go take a shower.
