I wanted to post one of my favorite books having to do with the Qur'an.
it is: Dictionary of the Holy Quran
I use it when i read the Qur'an because, as many of us who can't understand (fully) the Arabic know, the English translations often don't measure up. This book gives you an in depth look at the Arabic words. sometimes they stem from words you never wouldve thought of but when you know, it makes the Qur'an that much more awesome. i highly, highly recommend it... here is the link to amazon but feel free to get it anywhere you can find it. i found mine at Barnes and Noble.
