You would not sue someone in Superior Court for only two thousand dollars. Superior Court is for the professionals that you are accustomed to seeing on television in the courtroom dramas. Civil lawsuits can now be filed in some District Courts. In District Court, you file cases that are too large for Small Claims Court, but not large enough for Superior Court. In some instances, a jury trial is available for some civil claims.
All courts generally follow the same types of procedures and allow the same type of motions.
Even in Small Claims Court you may be required to know something about the law. It is very easy to file and litigate a small claim. That is the purpose of the specialized court. Whether or not you collect your money is another question altogether. You must go to the District Court Clerk's Office and obtain a Small Claim Form.
