I also agree with both Jason and Mark regarding the building of financial discipline. One way to force the discipline is to take the pay-down approach mentioned by Tracy.
Focus on a pay-off of the lowest balance, then use the low to zero interest offers they'll send you to transfer one of your highest balances to (or all of them if the limit will allow). Then pay off the balance with the highest interest rate next, while the other is in 0% interest. While you are paying down a specific balance, only pay the minimum on the other cards. It'* about focus and a goal.
Have you ever created a working budget for yourself? This is an important part of the financial discipline. If you have trouble creating a meaningful and honest budget, then definitely see the financial or credit advisor at your local bank/credit union. Unless you know what you are really spending on a weekly basis, you have no chance of getting your spending under control.
Financial discipline is just that, it takes regular work. You need to address it at least once a week until you have a very good handle on your expenses and spending habits. At first, you should really keep receipts for every little thing you buy, even the coffees, sodas, and vending machine purchases. Carry around a little memo book to write all the crap down. It seems ridiculous, but unless you do this for at least a month, you will never really know where all your money is going.
Most people find that they spend WAY more than they thought on the "little" incidental things during the week than they thought. Most find that simply reducing the number of times they go out to lunch and dinner can save them hundreds of $$ per month.
