Bryan Peterson's book is a very good starting point and only one of many books, articles and videos about the D7000. This is a very popular camera. Also, see if there is a camera club where you're stationed. That's another great source of learning photography, but the best teacher is going out every day and taking photos. Don't be discouraged if they don't turn out perfectly. Each of those photos are valuable learning tools to help you improve. Why did it turn out dark? Why did it turn out too light? Each photo has EXIF data that tells you about how the photo was taken.
There are a lot of features and settings for the D7000, but you can go slow in learning them. If you forget what you've set, there is an easy reset procedure to get you back to default settings. I don't believe there is a combination of setting that can actually hurt the camera. At worst, you'll get a bad photo.
I would stick with the Nikon camera battery for now to keep everything simple. You can probably take 1,000 digital photos per charge, but I would recharge at the end of a shoot so you have a full battery the next day.
Good luck with your new D7000.
