for Telnet: create an access list to deny telnet from your users subnet, and allow telnet from your management subnet. Then apply the ACL to the line vty 0 4
for ICMP: create an access list denying all icmp traffic to/from your users subnet in and out of the interface they're connected to (i.e. Interface FastEthernet 0/0).
