Coool, I'm glad that helped.
Yeah, a router would be best. Many people have a router of choice, but anything by Linksys or netgear should be quite easy to setup.
If you ever get other computers or PC's, you will also be able to hook them up too and share your internet connection.
Your router handles all your data being sent from all the computers connected to it and the information being accessed from the cable modem.

If you are going to be with NTL and have broadband through a cable modem, you will want a broadband router or cable router.
If you are going with a broadband ISP that uses an ADSL modem, then you will need a router that has ADSL.
