First, congratulations! This is a hobby you will love. If you have a Joanne Fabrics near you, sign up for their flyer, and you get coupons - 40% off, it is great to be able to get your stuff then.
I like the 24" Rotary Board, and the 45mm cutter, and you need a ruler that is about 23 or smaller. Get a good pair of scissors, and good small ones for cutting threads. Take a basic class at a local shop to show you how to use the tools, then you won't get frustrated. A really neat pattern easy for beginner is a disappearing nine patch, look it up on line and it shows you how to do it. Go for it! You will never be the same.
