Looks like you're on the right track. I just used the tank and regulator off the BBQ with an extension hose and adapter to fit the stove. Ran fine.
Did the same thing you are doing. Took off all the burners, cleaned, painted, polished and even replaced some of the hardware with stainless.
When the stove went back in trailer all it took was a slight adjustment to the pilot light.
Good luck, Tom.
