I'm not sure I understand what you're asking. If you're talking about a settlement of some kind I believe that only works if you are seriously delinquent and have gone into collections. You might be able to negotiate your interest rate if you are a good customer and always pay on time, but I've never heard of a credit card company just forgiving debt. HOWEVER, if you are not delinquent DO NOT purposely go into collections just to settle. That will kill your credit.
Do you have more than one credit card? If you are up to date on payments, then I would recommend taking the credit card with the highest interest rate and pay the most on it, while paying the minimums on the others. That method makes the most sense mathematically.
If you need it more on an emotional level, I hear Dave Ramsey's method works well. While I don't agree with everything he says, his method does work for a lot of people. On his plan you snowball the smallest debt no mater the interest. You can find his books online or at your local library. He also has a website.
