Is the scale meant to represent the sum of responses (each response is an element of, say, the set {1, 2, 3, 4, 5}) of a case (an individual) to a set of questions (items)? And is a "scale mean" the mean of the values of the scale variable in the entire sample?

Yes, the scale referenced when the model is Alpha is one created by summing the item values for the identified items.
