Ok,

I have a Comcast business gateway, IP Block is:

 ip:  xx.xxx.177.232
gw: xx.xxx.176.1

If I set the gw to bridge mode, will I just have to basically set the WAN IP of the SW to xx.xxx.176.1 and it should work?

If it a block of 4, then the other usable IP is used by the Comcast device and is typically one above or below your free IP address (so either 177.231 or 177.233).  So you would set the SW to use that IP instead of the 177.232

Within the constraints of the number of IP addresses above, your WAN IP should be xxx.xxx.172.232 and the other address is in the Gateway block.

Your iSP machine is.a modem. Make sure your router has assigned the correct external IP address

Please give us the exact information Comcast provided you, while filtering out the first 2 octets like you've been doing.

My guess is you should be using 177.232 or 177.233 as your IP based on what you've posted.
