Newbie Air Port Questions


I just got a new iBook 600 and want to go wireless, but I am unsure what to get or how to set it up. I currently have an iMac 333MHz and PC sharing a cable connection with a Linksys cable internet gateway. The Linksys has a static IP while the iMac and PC have DHCP turned on. Both of these are wired. I want to add my iBook to the mix.

Here's my first question. Should I get an Airport Base Station or a different one from another company? I already know I need the Airport Card ;)

Second question, how should I configure all the hardware?

Any info would help.
