I've got several trumpet books coming in the mail.
I'm a fan of the Rubank method. It leads you through the basics and beyond, constantly building upon what you learn as you go along, so success comes early and progressively, building both ability and confidence. It also introduces musicality right away, so you're not just playing notes and exercises; you're playing in a musical context.
