U need to know the exact port numbers for each chat program - or maybe the IP adress of the chatservers.
The problem with clients like ICQ is that they can connect through other ports like port 21. It then masks itself as FTP traffic and maybe you don't want to cut that service.
However with these chat programs they may be hard to block, but if you use port address translation, you will only be able to send instant messages. You can not share files, start direct chat and these kind of services unless you allow it through the FW, so it should not be that big a problem.
