Having given hundreds of reviews and received dozens, let me give you some insight into how to help yours turn out better.
First, as MogulMonster said, write up a little report on what you've done in the last 6 months and give it to your boss. Don't go overboard patting yourself on the shoulder, but modestly list all your achievements. You've probably done many things without your boss knowing, so here's your chance to get them in the record.
Were you assigned specific tasks, areas to improve, or other targets at your last review? Then make sure your report addresses how you achieved those targets and goals. Did you fail to meet a goal? Then address that too. Include the good and the bad.
If you give that information to your boss a month or so before your review, you'll be amazed at how much of your information finds its way into your review. Your boss will be thrilled at how much time you saved him/her.
At the review, make sure you ask questions. If you were rated below average on something, ask how you can improve or suggest a way to improve and ask if that would be a good plan. If you get your boss to agree on your improvement plan, and you follow it, it's going to be hard for your boss to downgrade you later.
Do you have ideas on what you want to be working on? Then first find out what your boss is supposed to be doing to improve the operation. Then make sure your ideas support what the boss is supposed to be doing. That will make your boss look better, and that will flow down to you. Suggest your ideas at your review.
