Hello,
Of course. I use zsh almost exclusively from within GNU screen.

GNU screen uses Ctrl-a as "prefix" for all its commands. To send
a "real" Ctrl-a to the process running in the screen window, use
Ctrl-a a.

This looks a little fragile. To check for a SSH session use one
of the SSH_* variables set by sshd, e.g. SSH_CONNECTION or
SSH_CLIENT.
if [[ -n $SSH_CONNECTION ]]; then
# inside a SSH session
fi

My current solution to automatically launch a GNU screen session
or connect to a running one looks like this:
if [[ $TERM != dumb && $TERM != linux && -z $STY && -z $TMUX ]]; then
# Get running detached sessions.
session=$(screen -list | grep 'Detached' | awk '{ print $1; exit }')
# Create a new session if none is running.
if [[ -z $session ]]; then
exec screen
# Reattach to a running session.
else
exec screen -r $session
fi
fi
This must be added to the ~/.zshrc on the server.
You can easily adapt this for your setup. Just change the
condition inside [[ ... ]] to something like
[[ -n $SSH_CONNECTION && -z $STY && -z $TMUX ]]
This condition is true if inside a ssh connection and neither GNU
screen nor tmux is already running.

man screen ;-)
Add "startup_message off" to your ~/.screenrc.
