I put the code in from the card right away. Then you can make sure the pics are of the right show. Only once were my pics missing. We were staying at the poly so went to the mm booth thing there and they were able to pull the right show and add it to my mm. The pics they take are awesome. When we did it, we would get to the park around 815 for 9 am opening and we were always done with sign ups by 9. The last time we did it there was a separate line by the turnstiles for jedi training. I would ask a cm where to to go when you get there because things change fast at Disney. I think you will be fine as most people are headed towards toy story land these days.
