You should obtain counsel to address the criminal matter as the outcome of that matter can impact you future employment particularly in the area of teaching or other government employment and licenses. An arrest occurs the moment a law enforcement officer takes you into custody and is separate and apart from a coviction. I encourage you not lie on an application as that can result in denial of employment or termination of employment once discovered. My office can assist if you wish.
The answer depends on the question. You really, really need to retain counsel to navigate you through this.

Assuming that you are charged as a juvenile and not an adult, your record will remain confidential now and in the future. However, to ensure that your record remains clean you need to have the charges dropped.
Furthermore, you should never believe that you are better off appearing in court without an attorney.
