You don't need Gold to get them, the free Silver membership can get those downloads. To get them, press the center button on the controller, and go all the way to the left and choose Redeem Code. Now type the 25-digit code from the preorder code, make sure you have typed it perfectly, and then select done.
That should register the downloads and bring you to the confirmation page.
