Greetings, Christine. I too am creating my first outfit for entrance into the 501st. It's nothing as grand as Jango, just an Imperial Officer. It is only a jumping off point, though. I am aspiring to one day get a full Empire Strikes Back Vader (the movie he seemed the most evil in, to me).
Welcome aboard and good luck.

(P.S.: Pretty much everyone at the 501st will tell you to steer clear of the Star Fortress pieces.)
