We have the same model rig. The other coax jack on the side of the unit is for Satelitte connection. Those connections should be the ones on the side opposite of the awning. The two under the awning are for you to plug your TV into when you hang it on the outside of the camper. There is a bracket there that matches the one where your TV is hanging on the inside of the unit. Just slide the TV up and off the bracket on the inside and take it outside and slide it down on the bracket there then plug the TV into the outlet and coax connector and you will have TV outside.
The lil black button under the TV on the inside is an antenna booster and is lit when you are using the booster. You turn it off when using cable hookup and turn it on before you scan for channels when using the antenna.
As far as the radio and the alarm that is an issue of long discussion on here. Some have found a way to shut it off and others have reported that they can not get it to shut off. I am not where I can scan and send you a copy of our radio manual. It will be over 2 weeks before I can do that but will be glad to once I get to the unit and retrieve the manual. You should have gotten one along with all your other manuals when you purchased it. Sounds like it was missing.
