Shipping and Payment Integration

I have a few questions before I start with the deployment of nopCommerce for our store:

1. If I download and deploy the nopCommerce 1.30 on the host, after that would I be required to explicitly add the modules for shipping and payment or do they come in the package that I download?

2. For getting the live shipping rates, would I be required to add the USPS, UPS modules or are they already integrated in the package and I just need to activate/deactivate them?

3. For payment processing (credit card), would that be already there or I need to add one of the payment modules in order to accept credit card payments?

1. They come in the package
2. You have to activate USPS/UPS to get the live shipping rates. They are already integrated in the package.
3. Payment modules are already integrated in the package.

I have a couple of similar 'Ecomm Newbie' questions:

If using PayPal (Express) - is there anything I need to set up in my PayPal a/c first, such as a merchant number?
Also, where do I configure the application to use my PayPal account - is this in the 'Administration/PayPalExpress/ConfigurePaymentMethod.ascx' file?

If I want to allow users to simply pay via c/card without necessity of logging into PayPal - is this the 'Manual Processing' option? This seems almost too simple to be true... is there anything else I need to set up / be wary of?


P.S. I'm very impressed with this application of yours!  :)

1. Go to Admin area > Configuration > Payment > Payment Methods. And click "PayPal Express" to configure this module.
2. Try "Paypal Direct"
