If you're new to Linux, I wouldn't have recommended Fedora. It's very up-to-date, very good for developers, but not necessarily the easiest to set up for new users.
As far as the wireless card goes, after a bit of Googling, it seems that it is supported, but requires a firmware download. Red Hat don't include these in Fedora (although other distributions do). This is available from
http://ipw2200.sourceforge.net/firmware.php
I've no idea of the driver version included in FC4 though.
