Shop diagnosed the car. The leak is coming from where I thought (upper rad hose), so they'll be replacing that as well as the temp sensor upon my request. I initially thought the thermostat was also stuck open, but they seem to be positive that the leaking hose connection was actually mimicking the symptoms of a stuck thermostat. That's great news and makes sense -- I found it hard to believe that a barely-year-old thermostat was already stuck open.
