Word doesn't have a referencing format that conforms to those requirements; it's implementation of Chicago is particularly poor. You could, however, insert all your references and the bibliography using the ISO 690 or Vancouver format and, when your editing is done, convert the bibliography to static text, then change the referencing to the IEEE 2006 format. The ISO 690 & Vancouver bibliography formats are closer to your required bibliography format than any of the others, though some editing will still be required.
