Unfortunately, Apple requires that a User creating a new account must enter the aforementioned information. Do so and log out.
Then log back in and remove all financial information.
Here's a video that shows how to setup an iTunes Music Store account.
We also recommend that a Debit card never be used unless the account it's linked to contains a small amount of funds that you are willing to lose.
It takes much less time to enter Credit/Debit card and PayPal information when making a purchase then it does to contact a financial institution for redress if or when an iTMS account is hacked.
One last word of warning ... never do a financial transaction from an unsecured wireless network. The convenience is not worth the risk !
