What should I expect at court?

I had a guy over my house who I thought was a friend. After I took him home I realized he had stolen 2 Wii video games and an iPhone from my home. The next day I went to the police dept to file a police report. He even admitted to stealing the item via text message. I took this information to the prosecutor and he agreed to press charges,. I received a letter in the mail saying the guy has plead Not Guilty and requests a court event. Then it has a trial time and date. I have printed out the text messages, the price of the games and phone, a a few other things that may be needed. It also says that he will not be represented. What should I expect at this trail? Will the prosecutor be present? What is the likely hood that the judge will order him to repay me?

He have to repay it; police court etc etc are for this only.
