Quick ?. Does the fork steerer tube have to be flush with the top of the stem? Thanks

No, but it should be close to being that point, because if it's too low, it might snap.

usually 1-2 mm below to allow for bearing preload. some riders who wish to preserve the length of their stem for future builds or resale will use spacers above the stem as well. maybe gain another 10-20mm that way.
