Using Category 5 (cat5 or cat5e) cabling for networking and phone will be your best bet. For cable you always want to use RG6 type cable, NOT RG59!

If you have a chance to wire your own house and feel comfortable drilling holes, pull two cat5 cables and one RG6 cable to everywhere a computer or T.V. will go. The best cable for a cable modem is Quad shield cable. It's expensive but it's the best.
