Your CATV company will determine what is best from the pole or pedestal to your home. As for inside the home, RG-6 will work fine, unless you are near a Hamshack or Am/Fm transmitter, then you may need to go with RG-6QS, which is harder to terminate the ends properly.
You also really need only one coax to the house, unless you are going to be doing Satellite, then you may need two. What really are you going to do once you do the coax? Are you also running Networking, whole house audio, video cameras, etc.? If you are, figure min. two Cat-5e or Cat-6 to each jack location that has a coax running to it. There is more to it, then just throwing stuff together, due to you really need a plan in what you need for connections for each room, and how you are going to do it.
