The quick and the dead, the rich and the poor, pros and cons, last but not least, etc., etc., is there a special name for this or is this just expression. Do you call them collation?

You could conceivably call this a collation, although it would have to be an odd collation in this case since everything but "last but not least" is an opposite.
This is a word that normally would only be used in some technical writing context. Collation isn't part of common usage in everyday conversation.
In conversation the word tends to sound pretentious.
Everyday usage would be "group of phrases" or "set of phrases"
Your example consists of a group of noun phrases.

Thanks. I was trying to say collocation not collation. But you think there are not more than noun phrases albeit being used extensively and there is no special grammatical term you know of.
