Getting started with LWJGL

Hi all,

I'm looking to get started with LWJGL. I understand the basic setup of the structure (with static calls made to the Display class) but I'm a bit stuck on getting into OpenGL.
I tried to do what I usually do and just sort through the Javadocs for it, but none of the methods have any explanations/comments for what they do.

Does anyone know of a good introduction to learning OpenGL online? Or a book I could buy online/get from the library?

PS: I'm looking to build a basic FPS from scratch. Any other suggestions are welcome as well.

Also, it would be preferable if I could get my hands on a guide that explains WHY and HOW things work to some extent. I hate blind-copying code, and I refuse to do it most of the time.
Learning how it all comes together is the exciting part.

Thanks,

//Caleb
