They don't show up in your post but I see you have golf cart batteries. You have 225 amp hours capacity for 20 hours but you don't want to use it all. You would be good for one night more than likely and have some spare capacity until you recharge with the generator.
Deep cycle batteries are designed to deliver a given voltage for a given period of time before they become technically dead. I have forgotten the percentage of capacity you can draw down before this condition occurs. There are charts, even might be one here that shows the level of charge at certain voltages and capacity.
If you are planning on using this system many times throughout the year you might want to invest in a meter that shows your usage to show you where your batteries are.
I left my solar house with 12 solar panel and 6 deep cycle 6 volters and all the other stuff that went along with the system, however I never paid much attention to my meters because I lived in a zone 6 sun isolation area so I only watched meters when the one day that came along when the sun didn't shine.
I'd say use the furnace at night and recharge in the morning.You should be fine and Mr. Heater will help greatly. I heated my immediate living space with one and had a muffin fan and snap switch affixed to it to move the heated air into the room.
