I request that in the checkout you make a seperate step in the begining that ask user is they are a registered customer or a new customer.
Because how you have it now with the login above the address is very very confusing to the average customer. I have already asked a couple firends and relatives and ALL of them were confused by this.

The first step should be like barnesandnoble.com or amazon.com or many many other sites.

It is better to have 1 extra simple fast step than to combine in a confusing way.
