definately check out Sun's site, where it gives sample exam questions, objectives, and general info. Then, I would reading some text like RHE where it talks about the prograqmming portion and the exam so you can kno what to expect. Then, maybe brush up on any areas of weakness. Then, just buckle down and do it. Don't know what else to say. Many of the posts on this forum have links to excellent sites. I have been to several. Read some posts, find some links, follow them.
