You could also look at FIFE Engine, and potentially investigate if any of the game projects based on it have source available.
Also, this one's a strategy game rather than an RPG, but Battle for Wesnoth might be worth a look as many of the features -- such as the map drawing -- are potentially similar to those needed for a 2d RPG.
Remember to take anything you see with a grain of salt though -- you're looking at the final resulting code, but you almost certainly won't have access to the logic behind the choice of that particular implementation -- you won't know whether a particular technique was chosen because it is the best idea, because it suits some special and unusual need of the particular project, because it used to be a good choice for reasons that no longer apply, or even simply because the developer was ignorant of better options.
Hope that's helpful, and good luck!
