I think the best layout would be to put 2 NIC cards on the Squid box. Like you said, plug the 1st cable to the firewall and the 2nd cable to your backbone switch where the 4 other sites connect.
The following diagram may represent the simple layout.

I would like the Squid box to run in transparent bridging mode. This way, you don't have to change anything on your network. Furthermore if your Squid box should go down, which is unlikely, you just reconnect the cable from your backbone switch to your firewall and everything becomes normal again!
Since we won't be running any firewall except for intercepting web requests to Squid's port, your VPN and SSL traffic should not get hampered.
In fact, I am using this setup on a Debian shaper box and so far it is working great.
Hope it helps.
Thanking you...
