SOA is actually in every mouth of every IT departament, so you must go for it if you just want show something "hot" for an employer. Personally, i think that you can go for SCDJWS and then go for IBM SOA, because there is a lot of questions in IBM SOA's exam that is related to Web Services. Also, IBM SOA is focused on IBM's SOA view, products and solutios, SCDJWS is "more neutral". Just my 2 cents.
