Will,
I gave my part I of
SCEA a couple of months back and it was based on J2EE 1.2 (EJB 1.1) specs..i.e. there were no questions on local interfaces, mdbs etc. Part II, I think, does not have any versioning restrictions. Many have architected based on 1.2, some have done it based on J2EE 1.3.
As for books, there are atleast 2 books out there, which are considered alrite..
1. Sun Certified Enterprise Architect for J2EE Technology Study Guide

For part I, there are loads of documentations available online. One good source is the yahoo j2ee_scea user group..it has some very good resources/reading material on part I. Join the group and you will get good stuff in their 'Files' section.
hope this helps.
