Have you seen our SCJP FAQ? That should point you in the right direction for most of your questions.

Do you have a good exam preparation book?

Also, there's no better way to reinforce your learning than actually writing code. Spend some time figuring out how to write programs that use these language constructs in various ways. (Except for the OO principles, which are harder to appreciate from small toy examples.)
