What do i do at this point?

im 16 yrs old n in sept. ill b 17. This week i was arrested for stealing 60$ worth of merchandise. This was my 1st offense for anything so when i was arrested my fingerprints and mugshot are now added with my name. ive been out of school since Jan2011 and have been working on an online download ged prep. im not ready to take the test but i think it has to b done soon so it will help in court. i was also thinking by getting a job it will help my chances as well but idk what else will. i just want to show that it was a first time thing and i don't want to end up in jail like my dad. i regret my actions terribly and just want to move past all this but i need to know what the judge will do to me and how i can prevent my consequences from ruining my life.
