1. When Ponyboy awakens. he notices that Johnny's jean jacket "Had somehow got thrown across me." What does this show us about Johnny?
Because he is a very good guy. His taking on the role of being the older brother or caretaker for Ponyboy. The reader already liked Johnny, but by Johnny deciding to sacrifice his own warmth and comfort for himself to keep Ponyboy warm makes us like Johnny even more. Therefore the label of "murderer" doesn't fit Johnny, and it becomes another example of labels providing an incomplete- and inaccurate - picture of someone.
2. Ponyboy doesn’t want to cut and bleach his hair with peroxide, but Johnny knows they need to alter their appearances. According to Ponyboy, how does a military or prison haircut serve as a method to break young men from their social class?
For the greasers, the group/gang his in one of their identities is their long hair which separates them from the others. By giving him a haircut means he has lost his identity and something he took pride in. The haircut is also a tool of humiliation in the justice system then.
