A curtain seems like the quickest fix for the water heater. I agree with the flammability concerns, but these can be remedied by spraying the fabric with a flame retardant, usually available at hardware or craft shops. this is the same type of spray that you would treat fabric with if you were making a lampshade.
As for the ductwork, why hide it? For a quick fix, oh sanrio freak, just hot glue a bunch of Hello Kitty's in cars on the sloped part. Your very own Kitty freeway.
