Regarding books material....
go through javaranch.com/faq.jsp

If you know core java than
Kathy Sierra and Bert Bates book is very good for scjp1.4 exam,
for scjp5.0 K&B book is not out yet but is expected in near future.
(scjp5.0 or 1.5 are same you may call it TIGER).
if you are new to java than reading Head First Java would be a good choice.
and than K&B book.

alot.
