On the matter of priscilla "teaching" apollos, this is an interesting article about how the word "explained" does not have the same force as "teach":

This then seems to be the line of demarcation that this text encapsulates (especially when it is compared to 1 Tim 2:12): a woman may explain the known facts of the gospel. But whether she has permission to exhort men on the basis of those facts is both outside the scope of Acts 18:26 and its context and is proscribed in 1 Tim 2:12.
Of course it is no problem for a woman to explain the gospel to a man. That is not the kind of teaching role that Paul is forbidding in 1 Tim 2:12.
