Can somebody please explain harry potter & the deathly hallows to me?

When he tried to kill harry the first time he killed the part of his soul that was in harry's body. Harry lived because his blood still survived cause its in voldomort from when he took the blood in the 4th book. Harry was naked i believe cause in his mind he doesn't need clothes. They were in his mind and i believe that Harry had all the answers he just needed dumbledore to point them out. He didn't know about the horecrux in Harry. and the Elder wand belonged to Harry cause he capurted Malfoys wand and Malfoy captured Dumbledore's wand who was the one who had it in the first place.
