With your background, Java certification probably won't make that much difference one way or another. You would, however, find the Sun Certified Java Programmer credential pretty easy, so you may want to take that one and re-evaluate your thinking with one exam under your belt. Again, given your current credentials I don't see it making that much difference to your employment chances. If not a single Java certification, why not consider pursuing a more advanced Sun or Oracle certification instead (the Oracle Java Developer cert is supposed to be pretty hot, and is said to offer a good chance of a low six-figure income).
