Listening on 0.0.0.0 listens on all network interfaces.
Mark's comment is not a major concern unless your KVM host is directly
connected to the Internet (no firewall).
* You should consider adding firewall rules on your KVM host none the less.

You can specify the VNC port when creating a host.
But as far as connecting via VNC to a host VM by name without also having
to add a port # suffix, that is more difficult. Easiest way for you to do
so is to create shell aliases for each one.
For my own deployments, I have a wiki page which documents what VNC ports
are used.
There's also virsh commands to extract info.
virsh dominfo <VM_name>
virsh vncdisplay <VM_name>

Yes, a manual process.
One would think there's a way to change it via virsh, but that could/would
be a problem for a running VM.
virt-install has options for specifying VNC ports.

They do not need virsh.
SSH to the KVM host and run the virsh commands from there.
