For Alliance the second and the third boss are swapped.

I can safely say as of 9.2.5 this entire Glory requires at least three characters, managed to complete it with two players and a 3rd character on a second account. Reason being the Council fight (Akunda's mind control), Blockade (you need one person on each ship and a 3rd one doing the achievement) and Jaina (three people needed to build the snowman).

Definitely easier than the Uldir achievements, regardless if you outgear it or not. You can expect to 1-shot most of them, while a few can take a couple of attempts to figure out exactly how they work. Once you understand how they work, there's none of them that is gonna be challenging.
