Ok lets clear some of this up, so you all get working properly first and foremost. In order to connect 2 computers to 1 WAN connect (Cable modem, in this case). It can be accomplished 1 of 2 ways. The easiest and preferred is via a Router
. That however is not the only way, If the main computer has 2 NIC, this computer can act as the router by using Internet Connection Sharing.
No lets clear up some of the misinformation out there.

Yes a router is best. No a Switch will not work as well, it does not have DHCP functionality, which means only 1 computer will receive an IP address.

Most DSL modems have routers built into them (which can be hooked to a switch) but most cable modems only support ONE device, so you need to use a router to hand out IP addresses to more than One device.
Yes and no, it really depends on the cable company and most are cheap as hell and will just give a modem with no router capabilities.

Switch: Switches are like routers without all the features. They connect more devices than what normal routers can connect.. i.e. like 8+ devices.
IMO. I run a Modem (Obviously lol), a Router and a Gigabit Switch. I use the Router for My PC, my mom"s PC and my Step Dad's PC. Then I hook a switch to the router to give me even more flexibility to connect more devices like Xbox 360, Printers (Unless you want them on a wireless network.) etc....
*Conclusion* Good Router, Good Modem, Good Switch and your set.
Routers partly correct. They are designed for breaking up broadcast domains
(i.e. broadcast segregation). Routers do not assign MAC addresses, they can
assign IP addresses if
DHCP is turned on.
Switches do connect multiple devices together, however they are connected via 1 broadcast domain. A switch breaks up Collision domains where as a HUB is 1 Collision domain.
