To redeem your gift card, go to the Amazon site and search for Gift Cards then click on"Apply a gift card to your account." . Find a claim code, on the card under grey protective coating and very gently scratch it off and reveal the claim code. Your purchases will be read in the "current Balance" and will remove the $ amount on your card, with each purchase. Enjoy spending!

I can not get amazon to use my payment method on books I already ordered.

You need to change the number on the Amazon site. Go to Amazon, your account, Manage payment options, will probably ask you to verify log in info, Click on Add payment method, You MUST set new card as default. That may be what you missed. I did it the last time I changed mine. There should be an option to delete old numbers.
