Ok then let's see
A. We (as in the player character) get to take our own body to the First as confirmed by Yoshi-P, thanks to a superpowered echo buff. Our Scion companions get new bodies though, it seems.
B. Eulmore is Limsa Lominsa if a completely different set of people settled there at a completely different time, and developed a completely different culture. The devs have not said a thing about 'updating' the old city states to work as one zone each.... Even if (especially in the case of Ul'dah) it makes no sense for the cities to be divided those ways, with the exception of Ishgard.
C. What Rongway said, but otherwise yes.

What we visit of 'Ala Mhigo' was the extra part built by the Garleans on the outside of the actual city to house the original inhabitants. We only ever visit 'Ala Mhigo' proper in the instanced dungeon.
