It seems like all the questions you have relate to the final four Spotlights.

Simon Furman had to wrap up most of his ongoing storylines in four issues after IDW decided All Hail Megatron would be a better direction for their comics.

So instead of being character focused, everything got crammed into these four issues rather than these four spotlights plus a six-part Revelation series.

At least some of the earth-bound plots got to be resolved in Maximum Dinobots, but even that had problems in the final issue trying to completely clear the slate for AHM.
