“I just wanted to check whether you think that v 11, 12b also refer to just this wife and husband at home? (Or do v11, 12b refer to what should occur in the church meeting?)”

Verses 11-15 are not about church meetings. They are about a certain situation to which Timothy was privy. Paul was giving advice to Timothy on how to handle a particular woman teaching error. The primary point and answer was that she was to LEARN, and she was to learn in the standard attitude of a student, quietness. Quietness is not eternal silence. Vs. 2 says that we are to lead a quiet and peaceable life, not a silent life. Same word.
