Magento - How to add customer default shipping address to adminhtml grid

I just was asked to update/change the Admin Customer Grid to show the default Shipping information.

So the new grid has  Email, Company Name ( custom attribute ),  Customer Name, Address, City, State, Postcode, Country, Phone, Group, Customer Since and Website.

First thing we need to create the module to handle this.  This is new module is called Dpc.

app/etc/modules/Dpc_Adminhtml.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Dpc_Adminhtml>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Mage_Core />
            </depends>
        </Dpc_Adminhtml>
    </modules>
</config>

<?xml version="1.0" ?>
<config>
    <modules>
        <Dpc_Adminhtml>
            <version>0.0.1</version>
        </Dpc_Adminhtml>
    </modules>
    <global>
        <blocks>
            <adminhtml>
                <rewrite>
                    <customer_grid>Dpc_Adminhtml_Block_Customer_Grid</customer_grid>      
                </rewrite>
            </adminhtml>
        </blocks>
        <helpers>
            <dpc_adminhtml>

Refresh your caches and you should have some new columns.
