You need to head over here. Then you will have to sign in at xbox.com. After that you will have to enter the following information:
1. The first four digits of your credit card number.
2. The card holders name
3. Your Gamer-tag.
I think thats the only information you need, but if theres more just give them it and your gamer-tag will be linked to your .NET passport.
