Access customer billing information during validate?

How would I go about accessing the customer information during Validation of the credit card?

[NonAction]
        public override IList<string> ValidatePaymentForm(FormCollection form)
        {
            var warnings = new List<string>();

            //validate
            var validator = new PaymentInfoValidator(_localizationService);
            var model = new PaymentInfoModel()
            {
                CardholderName = form["CardholderName"],
                CardNumber = form["CardNumber"],
                CardCode = form["CardCode"],
            };
            var validationResult = validator.Validate(model);
            if (!validationResult.IsValid)
                foreach (var error in validationResult.Errors)
                    warnings.Add(error.ErrorMessage);
            return warnings;
        }

What I'm trying to accomplish during this process is run it through our CC verification / encryption server to make sure the card if valid.

I know how to access it during the ProcessPaymentRequest() routine but not sure how to access it outside of there but in the controller.

Inject IWorkContext via constructor and use it: _workContext.CurrentCustomer

What reference class does IWorkContext come from?

I don't understand your question.
P.S. To get an idea on how to inject this interface via constructor have a look at BlogController.cs file (Nop.Web project)

I found that it exist within the Nop.Core project.  Sorry if I didn't word that correctly.

Thanks
