Multiple SSIDs and guest networks are pretty simple. It's typically as easy as going into your router config, enabling the Guest Network option, specifying the SSID and password, and checking the "AP isolation" and "client isolation" options
When you say "pubic" for your guest network and IoT devices, I think you mean that you want those things isolated from "your" network on their own VLAN.
