These are the results of running the commands. Does it look like there is anything that could be
interfering with port 3128 connections?

Could you advise of how I can determine if there is some firewall running?
To check if there is a local firewall running:
iptables-save
To check if there is a firewall between the client and the Squid server:
run "tcpdump -n -i any port 3128" on the Squid server, then on a client
run "telnet ip.of.squid.server 3128".

It seems you firewall is totally "open", i.e. it doesn't have anything
that could interfere with any daemon.
That "Connection failed" message puzzles me: if I try to telnet a linux
host from another linux host to a port that I know for sure it's closed,
it tells me "Connectoin refused".
So either we are using different telnet clients (mine is run under
gentoo linux) or there is something very strange goning on...
Have you tried to make squid listen only on the 3128 port ?
Maybe you could start from there and then enable one other port at a time...
(just writing thoughts as they pop off my head :)
