It depends on how much J2EE you know from your experience. For most people who venture in to J2EE world a few months before aspiring for the certificate, the list of books/references should be inclusive of *all* standard J2EE reference materials. However, if you have been in the J2EE playing field for a while and have had real-world design experience, you may only need to brush up your fundamentals and could pick up a certification just to prep for the test.
[ Digression - I have written about this before in this forum, and I am very tempted to take this chance to say it again. The people who can reap most benefits of SCEA certification are those who have been doing J2EE design and architecture for a while - at least for an year. Such people are presumably well versed not only with platform technologies, but also(perhaps) with the OO modeling techniques. Almost anyone capable of cramming can pass the first part however, part II certainly becomes easier for those who have done such things before for real. ]
Well, you get the point. Assess your J2EE competency on your own and then come up with a list of books and references. I highly recommend frequenting the J2EE forum and the SCBCD forum here on the Ranch for great discussions and excellent resources.

If you haven't already, I highly recommend reading this article, especially the section about candidate profile.
