The derogatory items are not going to come off by themselves and, if you do not defend against the action, default judgment will enter against you. That will also become part of your record.
The best way to bring up your score is to settle past debts and keep current on new obligations.

I must respectfully disagree with my colleague. Federal law requires that information be removed from your credit report after a certain period of time. Here is a link to the time periods applicable to various types of information that commonly appear on a consumer report: http://www.ohioconsumerhelp.com/sub/obsolete-CRA-info.jsp.
Note: the time may be LESS under your state's law, if any. But it can not report any longer than the periods indicated at the above link without running afoul of federal law. If it does report longer, you may have a claim entitling you to monetary damages.
The statutory period under which a debt may be collected through a civil action may be longer or shorter than these periods. But anytime you are being sued for a debt, or being dunned, whether you believe you may owe that debt or not, you have legal rights. I would strongly suggest you speak to a consumer advocate in your area to explore those rights and the best course of action in your situation. www.naca.net has an attorney search feature that will be useful to you to that end.
All the best to you.
Availing yourself of the opportunity to submit a question and receive answers to your question does not confer an attorney-client relationship with Amy L. Wells or WELLS LAW OFFICE, INC. The information provided is general legal information inspired by your question. This answer is not, and should not be construed as, legal advice. This answer should not be a substitute for obtaining legal advice from your own attorney, who may consult with you about the specific facts in your case, and advice you of your legal rights and possible remedies.

An affidavit of noncompliance will allow the creditor to remove you from a court-sanctioned payment program and get a judgment that will allow the creditor to step into the phone booth and emerge with a cape and a big red S on his chest as "judgment creditor" with access to all the court's post-judgment remedies, including garnishment and levying on assets. Not good.
As for the rest ... there's really not room here to explain everything you should learn in order to make the right moves.
