Don't worry. They will send you a interview notice to show what documents you have to prepare. For your case, I believe the important documents should include (1) documents from your local polce department about your arrest records (open records, you have to go the local office to request it and wait for 15 days to have it), and (2) all documents related the court processing (you can go to the court office to have certified copy from them). You may tell them the documents are for immigration interview, they will give you all information you need.
I suggest you to ask the IO (interview officier) what documents he really needs by checking his computer system. Typically IO has your submitted 485 package at hand. If you forget to bring the document IO needs or you did not prepare it, you can ask for permission to go home for it and return back to the IO (you have to remember the IO name so that the security guard can send your documents to the IO).
Be patient. Be polite. Business dress. I believe you are OK. No jail time, no problem.
Good luck,
