Rendering with a differnet name:??=* value.

I love that the tagging scheme of OSM is so versatile, and that there is so many multilingual values in the database. I'm interested in learning how to edit the map style, and render maps using any given language's name tag. What is the recommended approach for making an edit like this to the stile sheets for a personal project? Are some style sheets more conducive to this sort of editing, or editing by a newbie?
