So the "Second Kree-Skrull War" sounds like another fanon term that shouldn't actually have an article either...

To answer your question about terminology:
 * A Story Arc is a relatively short story that was given an in universe name and has a clearly defined beginning and end.
 * A Storyline is longer, was also given an in universe name, contains multiple story arcs, and may or may not cross over to additional titles.
 * An Event is a special kind of storyline that is basically a heavily promoted Crossover involving multiple additional titles, often referred to as Tie-Ins.
