Cut them up first.
Call the issuers of each card and ask for a lower rate. Offer to mail them the cut up cards, if that makes them happy. If they believe you're serious about shifting the balance to a lower-rate card, they'll match the lowest rate going.
Pay the minimum payments on everything except THE highest interest card --on that one, pay as much as you can. When it's paid off, cancel it and then do the same for the next highest interest card (because things that cost you 29.5% means in 3 years you've paid double whatever 'deal' you got the item for!!)
Continue until they're gone and then apply for ONE card, with a low limit, to be stored in the middle of a block of ice, or your safe deposit box --to be used ONLY to pay the deductible on an insurance claim and when you have saved an emergency fund worth all of your deductibles (total) plus 2 months expenses, cut it up and cancel the account.
Prepaid cards only, now.
