I used Road Runner with a router, now Comcast. I would let the cable guy set up the modem and cable system then put the router in place later. Then you know there are no issues with cable system or modem. With most cable systems you can run DHCP on both sides of router which makes the setup pretty simple.
Make sure you power down the modem before installing the router. Most don't lock to a MAC address anymore so it shouldn't be a problem but just better to start everything from a powerup.
