I just purchased a iMac G5 with an AirPort card already built in. My Titanium G4 Powerbookalso has a card as well. Are the AirPort cards compatible with a generic wireless router so I can link the two machines together or must I by an AirPort Extreme base station?

Yes. 802.11g is standardized and backwards compatible with 802.11b.
Any wireless router will work.

Better than that, Apple tends to implement standards better than most manufacturers, so when it says "802.11B/G" on a Mac product, it really is. And you should note that most third party wireless devices are substantially less expensive than Apple's. You can save a lot of money if you don't need the really cool styling.
