278417 Bug fix magento paypal

We need some fixes for magento. 1- Paypal processes the orders for us as payment gateway. But it seems that the order status doesn't change, even not when invoicing or shipping. Status of order stays Pending. 2- We use US letter size paper. So we need to have that set to US Letter instead of the standard A4. If you can help us with this please do so. Let us know ASAP. Also if you feel experienced enough to handle our new upcoming projects it would be great. I'm looking for a long-term team or person. Not a one-time "ass" :) thanks
