Yeah, ideally you never want two interfaces plugged into the same
switch like that. There isn't any point in doing so, and it's
considered bad network design.

There's a sysctl to silence the ARP warnings. I don't recall offhand
if m0n0wall has a check box to accommodate that or not, check the
Advanced page, it might be there. Otherwise google on that error
message and you'll find the appropriate sysctl to turn it off.

If you have a reason to use two interfaces like that, you should use
two switches, or VLANs.
