$1800 total in a 0% APR till 2007 Discover card, i'll try to pay it off before then

I have two other cards that I transferred the balanced from to the card mentioned ^ above.

I also have an AMEX Gold that's usually $1500-2500 in charges per month but I pay it off monthly.

What do you have?

Hopefully I don't rekindle any harsh feelings of indebtness
