Hi Eliot.
"Sun Certified Programmer & Developer for Java 2 Study Guide (Exam 310-035 & 310-027) (Paperback) " is for SCJP 1.4 and SCJD 1.4
"SCJP Sun Certified Programmer for Java 5 Study Guide (Exam 310-055)" is for SCJP 5.0. I bought this book for SCJP 5 preparation and if you study it very well, you can pass the exam with a good score.
In the cd included you'll find some useful chapters for preparing SCJD.
A good choice for SCJD 1.5 preparation is "SCJD Exam with J2SE 5" by Adnrew Monkhouse & Terry Camerlengo.
If I were you, I would go for the SCJP 5.0. It's a very tough exam, but J2SE 5 is full of exiting news and passing the exam will give you a great satisfaction for several months
Best regards and good luck for your study.
Barry.
