1. Canonically, the battle of Carteneau was (I believe, anyways. Don't quote me on this) roughly 1~2 months after the lunar transmitter was destroyed. Van Darnus went into hiding for awhile before raising the Rivenroad into the skies, and the battle of Carteneau took place not long after his defeat. All of the events during the Seventh Umbral Era storyline take place over the course of one year in canon, though in real life they spanned about two.
2. The attacks on the sultanate appear to be non-canon. Said attacks were occurring alongside the Battle of Carteneau in-game (which was canon), though the opening cinematic shows people calmly standing in Ul'dah watching the meteors trail off Dalamud. That seems to conflict with the idea of Chimera's assaulting the inside of Ul'dah like they did in-game. In fact, it wasn't only Chimeras, but Imperial soldiers, Qiqirin, Morbols, and even dozens of Van Darnus NPCs.
All of that seems to point to those specific events being non-canon, or at the very least, they likely would have taken place outside the city. Ul'dah is known for being pretty impenetrable, and it's highly unlikely that a few beasts could knock down all the gates leading into the city.
However, other people might feel differently on that specific subject. That's just my take on it.
