Best Practices for Class Renaming in Development Projects

Any documentation out there on recommended class renaming philosophy/approach? Getting to the point in the build where we're pretty set on our selected layouts/components. Perhaps it may not be necessary but I'm assuming theres some cleanup-related benefits to culling down the class list and systemizing some of the naming? And theres always room to add more layouts at some point so just trying to find the right when & how to start tackling that process. Thanks!
