I do think I understood your question proper.
If you are using a layer 7 switch then there is NO specific changes needed
to squid.conf to make things work proper. Just configure each Squid server
as you would normally configure this Squid server.

You should not.

Normally the IP address of the server where it runs, which in nearly all
cases is what you want.

This is up to your OS configuration, but in nearly all cases involving
layer 7 switches the OS will never use the virtual IP for anything except
accepting traffic via the layer 7 switch, and this is what you want.
You can ask squid to hint to the OS what address to use by the
tcp_outgoing_address directive, but you should only use this if your
situation requires you to. Only the fact that you use a layer 7 switch
practically never requires you to use this directive.
