Oh you guys work so hard on the replies, on the days I check my posts, no one every replies this quick Lol!
Alright well I'm not sure how aware of this website Birdtricks.com this forum community is, or if anyone follows these guys on facebook, but I really do love their birds and the people that train them, I recommend you checking them out and their youtube vids. Their training videos are super expensive, but they seem to have helped a lot of people
correct positive reinforcement and condition can go a long way! They were my motivation to switch my birds onto organic pellets/harrison's pellets, flight training, recall training and target training. Ofcourse Kiliparrot's videos on youtube also motivated me a lot! But these guys have experience training birds that were not friendly in the beginning so I hope you can investigate and check it out.
Macaws are loud, no matter how big or small. Screaming is also quite difficult to deal with, but it can be "fixed" and controlled. I've seen a vet who taught her umbrella cockatoo to scream on command so that she could get it out of her system on the vet's terms Lol. It was great!
But I remember you mentioning that you're moving soon -- you can keep visiting the bird but wait until you move? Perhaps that will give you guys time for bonding and time to fix the noise situation or accommodate it rather?
there's also this rescue
http://www.zazushouse.com/Welcome.html they take in macaws mostly, they have an outdoor, and indoor aviary dedicated to macaws so maybe you can get in contact with them because macaws are mainly their speciality, as well they have a special needs section where they take in macaws that were plucked and they are wonderful too!
I hope this helps, and with regards your name dilemma, I usually name my animals after I get to know them -- I like that you try to name them from their place of origin which is really awesome! Sometimes, the name can make the bird, but the bird can also conjure up its own name

Sometimes, birds won't go into breeding or nesting behaviour, and because it has been plucking, it may not want to lay eggs if it's a female. Macaws also mature sexually a bit later, I mean my green-cheek conure is going to be 7 in January of 2012, and she has not laid an egg yet, but displays some mating behaviour sometimes.
And the inconsistent "background stories" you're getting, keep in mind, not all employees are informed the same, some are new, some have been there just as long as your bird. Perhaps get in contact with the manager or even owner? or talk to someone who's been there for a bit longer. But usually a change in housing, diet, environment and some TLC will improve a bird's life.
