If you have already bought the router, use it. If you do not have a firewall, people will hack into your computers. If you don't have a problem with people seeing everything on your machine, or potentially vandalizing it, then don't worry about it.

The router is just plugged into the uplink on your hub. Some routers come with more than one LAN port, so you can plug computers directly into those as well.

Most routers have the ability to do NAT, which is the ability for one IP address to shared among multiple clients. When operating in this mode, it is the DHCP server for all of the connected computers.

You also need to make sure the router is configured correctly to talk to the cable modem. It can ask for a dynamic address, or it can used a static IP address. It can also do PPPoE, which is a method for authenticating the router as an authorized device. It all depends on how your computers got configured when you connected them to the cable modem.
