You can swap
KH2FM and
358/2 Days around if you want.
358/2 Days spoils some stuff in
KH2, but at the same time, it helps explain some of the more confusing aspects of it and provides a much better flow to the story. It originally released after
KH2 though, so either order works.
Also, don't be afraid to just watch summaries / recaps of
358/2 Days and
Re:coded. Actually, the versions of those two games on PS3 and PS4 are just cutscene compilations. Similarly,
Back Cover is just a movie version of part of the story of
x /
Union Cross, but from a different point of view.
