It doesn't tab between the input boxes or even show the boxes until it's detected the card type based on first four digits. On initial load you get an input box with "XXXX XXXX XXXX XXXX" and nothing else. It does not look like an average credit card form and a lot of people will be confused "where do I put in my name" when they first see it.

I don't know. The current convention is always to enter the credit card number first, then the name later (usually as part of the billing address). Once you start entering your card, the rest of the information is explained nicely.
