You will have to buy the touch screen from amazon, eBay or other component website.
A good computer shop should be able to replace broken parts to fix this.
Well... you really can't if you wan't to do it by yourself. Since your screen is broken, call or email Apple about what happened and they will either fix your screen or get you a new one. They would do this because it's included in your warranty.

You cannot fix it. It is broken and cannot be changed. You must get a new one or something.
