I agree that having the interest rate would be helpful. However, on first glance - I would suggest paying the firestone off and putting $500 on each of the other ones.
That said, I would really recommend paying them all off before trying to buy a house. You want a 720 midscore for best rates and you also want to have cash available for closing, fixing the house, buying new things, issues that might come up, etc. Therefore, I would try and pay them all off ($2,000 now, $2,400 more asap) and then have AT LEAST $5,000 more in cash for the house stuff before you start shopping around. That will also give your scores a chance to rise (pay the CC off in full every time or quit using them until you have the house). If that takes another year, so be it but at least you'll be more prepared and in a better situation debt wise. Finally, figure out how much more the mortgage will cost you each month and put that amount into an account (pay yourself with it - use it for the card, the $5k, whatever but save it) and that way you'll be used to paying that amount from your budget when you get the house.
Good luck!
