Whether or not you expect the tenant to appear in court, take with you into court all the records you possess on the tenant you are evicting.  These should include whatever is applicable from the following list: rental agreement or lease, pet agreement, condition and inventory checksheet, waterbed agreement, correspondence, certified mail receipts, invoices covering repairs of damage, collection records, notices, photographs, and even a chronology of the events in your deteriorating relationship.

Such records will strengthen your case much more than anything you are likely to say in court.  Judges do not really want to hear you and the tenant vent.  They want hard-and-fast evidence.
