@saintclair:
In order:
Workers of any race typically choose the closest available food/drink, regardless of their preferences or your convenience. I've been remedying this issue by burrowing vampires away from the dormitories/bedrooms, perhaps you can try something similar?
Are you sure you had hourglasses to spare? I'm pretty sure hourglasses get destroyed in the creation of phylacteries, which would necessitate constant production.
Living stone has been bugged for a while, just ignore it.
"Gender-neutral" citizens apparently choose a gender on world-gen, just accept the marriages as proof that warlocks are depraved and move on. (Bonus, sometimes the lovely couples will have children somehow.)
No idea, they might just have a long incubation period.
Did they die? You don't get another one if they die.
Hunting requires the use of a ranged weapon, which ghouls cannot use effectively by design. What you're supposed to do is assign all of your "hunters" to a military squad, then you issue a squad order to make the "hunters" kill a target. More/better information at the wiki,

I think animal hauling is a low-priority job, I suggest making a few skeletons or ghouls just for hauling.
