Have read ME1: The Progressers in Chinese just now. A good manga chapter overall. This chapter basically showed the duel between Kirito and Asuna over differing views on how to defeat a floor boss. Note that the front line in this manga chapter was 56th floor.

And there's a sentence at the last page that indicates the timeline of this chapter:

Spoiler for The sentence:

"Those two (Kirito and Asuna) got married eight months later, two weeks before the clearing of the game."

Whether ME series are canon or not is still a debate among the fan base because the storylines of ME series (including Aria) has many conflicts with the storyline of LN Volume 1 and 2. Some treat the ME series (or essentially the new side stories for first three floors such as Aria, Rondo) as canon while others not (think that only the storylines in Volume 1 and 2 are canon).

Basically, I just categorised the storylines into two categories: old SAO (Volume 1, 2 and 8) and new SAO (ME, Aria, Rondo etc).
