[Netgear]---[UTM]--[8-port switch]--[Internal devices]
And, you're right that you can just take the Netgear out of line and the UTM should grab a public IP from the modem.
The usual recommendation with a wireless router is to disable DHCP and tape over the WAN port so that you can use it as a wireless switch behind the UTM. When you're ready to do that, I bet there's a way to do a factory reset of the Netgear so that it has the default credentials for the admin account.
