I'm new to this module (and relatively new to SilverStripe and PHP) and am learning to use the 0.6 beta version in an installation of SS 2.3.3. I see that this module is designed for people in Europe and other parts of the world, but I need to use it in a site that's primarily for a U.S. audience.

I had found a post in the forums, that's nearly a year old, where someone had localized the module for the U.S., but the files provided don't work in this version of the module. I'm wondering how I go about adding State and Zip Code fields to the checkout page. I see on the documentation page there are some instructions for order form customization, but it doesn't tell you what file(s) to make the customization in. Can anyone point me to the file(s) that need editing for those new fields to get added to the database properly and to show up on the page, as well as get sent over to PayPal (the payment method I'm going to be using)? I'd actually like to completely remove the Country field as well.

I'd also like to be able to make sure any dates are shown in MM/DD/YYYY format, if possible. I understand that this module shows them DD/MM/YYYY (or something similar).
