First of all, always pay more than the minimum.
Secondly, it's gonna be pretty tough to play any kind of percentage game with a $70 CL. Ideally, you let under 10% report to the credit agencies and then pay that off before your balance due date, but 10% might even wind up being less than your minimum.
Can you post what you know about what the minimum payments would be? --it's probably something like 4% of balance or $10, whichever is greater. You also should call the company and find out when they report to the CRA's (credit bureaus), when they post the statement, and when the balance is due. If you can find that out and post it, too, you should be able to get some good advice here. It's going to be like walking on eggs with that card, though...
There have been some posts about Tribute. You can type in tribute in the search box at the top left and pull some up. Here's one (I'm on Firefox, so you'll have to copy/ paste it into your browser window):

This card sounds like it's going to have to be handled with EXTREME care!
