Assuming the instant messenger clients use standard ports/hostnames to connect to, ipchains/iptables would be the appropriate tool to block the clients when they use their own native protocols.
Some IM clients allow you to proxy through HTTP. I guess these would take their route through squid, and the squidGuard - but assuming the hostname is static (like. instantmessenging.domain.com), and instantmessenging.domain.com doesn't hold a website it could be blocked by ipchains/tables (although personally I would prefer to block this through squidGuard).
