If you have enough time for studying for a certification, you should
go for the exams right away. It is a good experience and a valid
addition to your cv. If you don't have much time, I'd suggest to plan
for an exam in a couple of months and study a bit every day.
JavaRanch was a great help when I had to certify.
Cheers and good luck,
