You can like you said, connect the modem to your router but I'm not sure if you can assign this modem an IP and let the router do the NAT. It depends also on the router model. You can also connect the router directly and replace the mode, keep it a side and forget about it. You will need it when you face a problem later and needs Q-Tel to test something. They will request the original modem to make sure that the problem that you are facing [hopefully you will not] is not from their side. That depends on your usage, if you want a router with good range of wireless then 3Com is a good one. Linksys also can be a good one, but got some issues sometimes , with the disappearance of the signal all of a sudden for a while and then coming back. Both of them got 4 ports in the back. Don't buy a D-Link, it is hopeless, The Netgear got a good wireless signal, but overheated quickly.
Depending on which series are you getting the prices will vary [for the Linksys] There is an 'N' and 'G' series. The 'N' series is the latest, got 108Mbps instead of 54Mbps [Wireless] and the range is greater than the 'G' series.
Prices:
3Com 240 - 260 MAX. If he asked for more, grab him and call the police :)
Linksys 'N' 640 - 750
Linksys 'G' 300 - 340
