Hello,
IAS services on server 2003 can give a methode using EAP-TLS (certificates), MS-chap v2 (handshake or password) and more.
for the ip phones you should use mac authentication by setting the ports on static (the ports which connect to the ip phones ofcourse).
on the downloads page of you 4500 switch you can download many configuration example pdf files. which are pretty useful. too bad there isn't an complete manual. i have already been looking for it. in case anyone finds it, please do tell me :).
