You could file bankruptcy, yes, but you have to appear for your bankruptcy meeting as well as you would have to appear for a small claims matter. (If the landlord doesn't have a judgment against you get, it's better to file bankruptcy before he gets one). It might be a good idea to sit down with a bankruptcy attorney that won't charge you for an initial consultation, and discuss your options.
Your obligation is to pay him what you owe under the contract--not what you feel is fair. Unless you can show a court what you feel is fair also is the actual amount owed.
If you fail to show up, or be represented by counsel, at court, your LL could very likely get a judgment against you--the court procedure will occur with or without you. Once LL has that judgment, LL can take action to place liens against yoru personal property or garnish your wages. That would NOT be a good way to start off your financial recovery. Recommend you see a NJ landlord tenant attorney (or contact any of the many NJ legal aid organizations and use a volunteer attorney) to fight the LL/or settle with LL now, before you leave the state the prospect of returning for court becomes so seductive you blow off the matter entirely.

Bankruptcy is not the answer. Your lease states what you owe each month in rent and additional rent (if the LL listed fees as additional rent). After you vacate the premises the LL is permitted to deduct from your security deposit what is specified in your lease. Your LL cannot deduct outstanding rent from your security deposit until you vacate. The proceeding is filed in the special civil part not small claims. If you do not appear the LL will be given a default judgment - that you owe whatever is outstanding that is delivered in the notice to you. The only defense to the outstanding amount is 1) you can show that you paid it via a reciept - money order, check etc. 2) that the LL is attempting to collect an amount that is not specified in the lease. Otherwise the court will go with the LL amount.
