You can just join the tables. No need for outer joins or anything according to your current data definition.

SELECT * 
FROM Orders o, customers c, orderstatus s
WHERE o.customerid = c.customerid
AND o.order_status_id = s.order_status_id
AND c.firstname = 'OM'
AND c.LASTNAME = 'The Eternity'
AND o.orderid = 752
AND ...
