This is one of the best articles on J.R.R. Tolkien I have ever read. It's quite long, but an extremely interesting read into his life and works.

I urge you, if you haven't read The Lord of the Rings, do so before the movie comes out. While I'm sure it's going to be a good movie, you'll never be able to achieve the wonderous imagery that the book can deliver. Don't forget to read The Hobbit too.
