Answer 1

Have you redirected the buyer to PayPal checkout page to authorize the billing agreement? As stated in the guide:

The buyer must log into PayPal once to authorize the billing agreement.

You'll need to redirect the buyer's browser to PayPal with the token, which allows the buyer to log into PayPal and authorize the billing agreement, then PayPal redirects the buyer's browser back to your return page(the one you specified in SetExpressCheckout). After that you can call CreateBillingAgreement with the token.

Hope that helps.
