If you can do marble than granite is no different to install so you should have no problem. Granite is a much harder stone than marble so cut slowly and be sure the blade doesn't bind up. Hopefully you will be using a wet saw as opposed to a handheld (unsafe). Other than that I would recommend using the new wedge levelers by QEP for a perfectly flat finish with no lippage. Good luck!
Here is a link to the wedge levelers:
