We used amonia and water 50/50 mix to get the sticky off the walls and ceiling and then gave everything a coat of clear floor polish (Brite). Looks great.
Our gaucho is missing too. We are completely revamping the living space to the way we want it. There are no hard and fast rules when you are bringing your trailer back to life (unless you are a purist). We are putting a combo entertainment/computer center in the front with other comfy chairs. Of course, we have a little bigger AS than yours.
As for curtains, there are professionals that make them, but it's also fun to dig through the Penney's Outlet bins for pleated drapes that can be adapted. When we got our AS, the previous owners had installed miniblinds. They worked, were dirty, but they worked.
Good luck on your project. Don't hesitate to ask questions. We are all pretty much in the same boat or have been at one time or another.
