Have a look in the etc/e directory in the emacs distribution. There you
will find an emac terminfo file which may improve capabilities (though
I'm not sure if shell uses this, but M-x term does. 

I'd try using M-x term rather than M-x shell as that provides a more
term compliant interface rather than just a dumb  shell. 

I don't know much about zsh, but it could be that emacs is executing it
as a non-login shell and it is not sourcing 'normal' login config files.
A couple of htings to try would be 

1. Start a zsh and run emacs from within that. Then M-x shell would be a
shell that is a sub process of emacs, which in turn is a sub process of
your zsh, so maybe environment settings will be passed along. 

2. You may be able to set explicit command args within emacs that will
be used when executing the sub-shell. Maybe that will give you the
control you want. I'd look at the cusotm groups for shell and term and
see if anything looks promising.
