Source: 6 Minute English - What’s in a name?
That's what we're talking about in this 6 Minute English. A husband taking a wife's name after marriage. All that, six related words and our quiz question.
What does "all that" mean in this context? I guess it could mean "and".
I think it simply refers to what was said previously. I. e., one could expand it to say, "So, we are going to discuss all that (the topic of husband taking a wife's name), we'll introduce six new words related to the topic, and we'll have a quiz question."
It could be a commentary on the social issues involved with a husband taking a wife's name after marriage, and the incongruity of fitting 'all that' into a 6 minute English lesson.
