Suggested Ports

Can anyone suggest the ports that need to be opened for a non-transparent proxy.  Currently I have the outgoing firewall blocking port 80 and 443 to force my users to utilize the proxy.  All other default outgoing ports are enabled.  My current proxy settings are as follows:

80 # http
21 # ftp
70 # gopher
210 # wais
1025-65535
280 # http-mgmt
488 # gss-http
591 # filemaker
777 # multiling http
800 # Squid (for icons)
8200 #Gotomeeting

SSL:
443 # https
563 # snews
3001 # ntop
1025-65535
8200

I would like to lock things down a little more, but I do not want to block certain websites from running optimally.  Any suggestions are appreciated.
