Here's my query to get all US deliverable addresses.
SELECT CONCAT( c.customers_firstname, " ", c.customers_lastname ) AS FullName, ab.entry_street_address AS Address1, ab.entry_suburb AS Address2, ab.entry_postcode AS ZipPostalCode, ab.entry_city AS City, sa.abbrev AS StateAB
FROM cart1_customers c, cart1_address_book ab
LEFT JOIN cart1_zones z ON ( ab.entry_zone_id = z.zone_id
AND ab.entry_country_id = z.zone_country_id )
LEFT JOIN cart1_countries co ON ab.entry_country_id = co.countries_id
LEFT JOIN mailing_lists.stateabbrev sa ON IF(ISNULL(z.zone_name), co.countries_name, z.zone_name ) = sa.name
WHERE ab.customers_id = c.customers_id
AND ab.address_book_id = c.customers_default_address_id
AND (
co.countries_name = 'Guam' OR
co.countries_name = 'Puerto Rico' OR
co.countries_name = 'Virgin Islands (U.S.)' OR
co.countries_name = 'American Samoa' OR
co.countries_name = 'Marshall Islands' OR
co.countries_name = 'Micronesia, Federated States of' OR
co.countries_name = 'Northern Mariana Islands' OR
