I think that Monterregiano is a region in Tuscany, it's not on the way to La Spezia from Milano.
If I did stay in Pavia or somewhere down the line, I would buy a seperate ticket from Milano to there.
What I was saying is that I have a ticket for Day X between Milano and La Spezia on Train Y (a specific train (in this case, an IC) at a specific time on Day X). What I am saying is that I presume that on Day X, I can get on and off train Y at any points between the specifically-ticketed points (Milan and La Spezia). Pavia and Monterosso happen to be stops for train Y on Day X between Milan and La Spezia.
And yes, it is Monterosso that we're planning to get off at.
