My question involves criminal law for the state of: NJ

Heres the story...Me and a few buddies went to a local 7/11, I usually never steal but my thirst got the best of me and since I didn't have any money I made the stupid decision to steal a Red Bull and a Pepsi. Little did I know that there was 3 undercover cops outside the 7/11 watching us the whole time. When we went back to the car one of the undercover officers approched my window and told me to step out of the car. He was really pressuring me to tell him that we had drugs, which we didn't. They searched my car for the drugs they were sure we had, but after they found nothing I was arrested for stealing the red bull and the pepsi. I am 18, and never had any run ins with the law besides a few traffic violations. I am about to start college and have my whole life in front of me and I really would appreciate some advice on what I should do. Will my future employers see this on my record? Should I get a Lawyer? What should I do/say in the court room? How should I Plead?

My court date is August 20 so I would really appreciate an answer before then. Thanks
