Depends what you're trying to accomplish. If just want the component structure to be translated ion two languages, then the ini files are the way to go. For example, the drop down box that says "--Select a teacher--" is an example structural translation. We have several ini files for various languages in the download section that provide these structural translations. If, however, you also need to translate the message (sermon) itself, you would need to use the joomfish content elements (download section) to do that. Joomfish and the INI files go hand in hand, however.
Hope that answers your question.
