| A cable modem router will help greatly with computer to computer transfers, but you won't see much difference at all downloading from the web. At most, you're getting 3Mbit off the web... an Airport's 11Mbit connection will more than handle that. If you were talking about connecting more than 5 computers to the internet, then I would lean toward the router.
I use a router to connect my PC, an old Performa 6400 and an Airport base station to the internet. Then I connect two iBooks to the web via the Airport. I haven't had a glitch. Downloads are fast, connections are good, and the portability is very nice. I love sitting on my balcony when there's a cool breeze surfing the web.
Turn on NAT on the Airport and you should be fine.
