I brought a garmet bag for my jacket. Just fold it in half and lay it in the luggage bin for the flight. Also bring a lint roller...

As for bringing a bag for the books. No way, the cool part is walking through the airport later and getting all the thumbs up from every pilot as you walk to your gate! They see those books you are carrying and know exactly what you just went through. Haha... They are cumbersome though, and bag is not a bad idea actually.
