In terms of books, I would suggest the Arduino Cookbook, Getting Started with Arduino, and Programming Arduino. While these books are helpful, you can actually learn easily without any books. For me, owning the Sparkfun Inventor's Kit was enough to be able to learn everything I needed. The way I learned best was trying to come up with a project far beyond my skill level, and then searching the Internet to learn how to do each component of it. There is a lot of free information out there, I don't think you're going to have any trouble learning the world of Arduino, even if you didn't get any books.
I wish you luck!
If you ever want to upgrade it, here is a nice one:

I've always fantacised about something like this.
Can you also include a feature to obscure my license plate and retract the gun to a hidden configuration.
I promise to only use this when appropriate.
