For the payment modules, since you use Papal, I can do some of that. The new shop uses a different set of files but the credentials are the same. You use the Paypal Pro and Paypal Standard modules in the live shop. For the new shop, you have to use Paypal Express when using Paypal Pro due to the code following the rules of paypal. So you have to add paypal express in your Paypal account. It doesn't cost anything but it has to be setup and I can't do that for you. There's no charge for help in setting this up.
