i'd start with the Essential Judge Dredd collection if you are completely new and just want to learn more about the world and the character. You can read them in any order, it doesn't really matter. You don't need to read the progs.
As for the movie, its pretty good, but its missing some of the tongue in cheek satire that the comics have. It does respect the story and characters, but in a perfect world i'd love the camp of the Stallone movie blended with the action and tone of the 2012 movie, if that makes sense
