Another Ramsey convert here.
There's a forum, livinglikenooneelse, and they can really help you.
One of the things that is suggested that, until you're out of debt, to stop contributing to the 401k. So instead of taking a loan from it, if you're contributing right now, stop contributing and use that money to throw at the debt.
And they do say to go lowest to highest *balance*, and ignore the percentage. Reason? To get balances demolished as fast as possible, and have "early wins" to help bolster your confidence that you can do it. It was easy for us, as after we smashed some ancient medical bills, our lowest balance was also the highest interest. Not as easy for others, to watch that interest pile up. But paying stuff fast really makes you feel good.
Good luck!
Bold - I thought that rule only applied if you could pay-off all the debt in a year or less.
