On the note of apparation, Harry actually learned to do so in his sixth year. It took him some time, and he was even too young (unlike Ron and Hermione) to take the apparation test at the end of the year, but when Dumbledore was weak and unable to apparate himself and Harry out of the cave after getting the fake horcrux, Harry had to do all the heavy lifing for that, and brought them safely back to Hogsmead. Between then and the end of the seventh book, Harry surely would have had time to perfect his apparation skills if they weren't good already, so I'd say his potential use of apparation would be a valid argument in this fight.
