You should block the ports used by applications you want to block.
Skype:

Messenger:

and
http://www.microsoft.com/technet/isa/2000/maintain/isaimsec.mspx
And so on. Look for them in the search engines. Alternatively, you can sniff the traffic to see which ports the application uses.
Also, you should restrict port 80 to HTTP traffic only.
