Change billing fields when editing admin order

Hi there,

when I edit an existing order in the admin, the (billing) address fields are shown like:

<first name><last name>
<company name>
<street>
<city>
<postcode>

<street>

<email address>

First off, I have no need for showing the street twice. And I would like to show postcode before city. I am having trouble finding the hook the change this format when editing an admin order
