Before you buy any books check out the local library but also check out the internet. There is so much information to be found for free. Free patterns galore - more than you could ever make. There are free lessons on U Tube and so many tutorials here on QB. Also lots of willing helpers which I'm sure you'll have noticed if you've been reading the posts.
Look around first before you spend a lot on books, rulers, etc and save your money for fabric. Ask me how I know this. Google Quilting for Beginners as well as Sewing for beginners.
Welcome to the board and remember there is no such thing as a stupid question. If you don't know just ask.
Happy Quilting.
