I have a date to attend a case management conference due to a credit card debt. What will happen if I don't go? What will happen at the conference.

If you don't show, most likely a judgement will be entered in the creditor's favor which they can use to attach your assets.

What will probably happen at the conference is they will attempt to show why you should pay the debt and you will try to show why you shouldn't.

What do I need to bring? Obviously I am trying to get out of paying the debt to the best of my abilities.

I have a problem with "trying to get out of paying the debt". If the debt is valid you have an obligation to pay it. If your circumstance are such that its an extreme hardship to pay, then try and work out an agreeable settlement. But I won't assist in stiffing the creditor.
