Wolf, I thought posting the video would be good for other people to see that this was not the behavior of a scared bird (it's hard to read behaviors accurately with birds so actually seeing an example helps a lot).
Now, on to the questions.
Cage, if it's going to be mainly for sleeping, it's a fine cage but put it higher so his roosting perch (the one he sleeps on) is at your eye level when you are standing up.
Perches: if you have other perches in there that are thinner, it's fine (I couldn't really see well into the cage and the ones I saw in the front all looked as if they had, more or less, the same thickness).
Hut: that one is fine. The material inside is soft but not piling. And, yes, put it high in a back corner.

B002DR5U9YLight schedule: uncover at first light and cover when it's dark (the idea is for the bird to be exposed to dawn and dusk from beginning to end but you can cheat a bit on the beginning because, otherwise, you would have to uncover at 5 am during the summer -I do it but I am not what you would call 'normal' when it comes to my birds care). Always say the same thing when you uncover and when you cover (I say "Hello. Good morning! How are you?" and, at night, first I talk to them calling them to me and scratching their head, cheeks, neck through the bars and then I say "Nite nite Tsk tsk tsk tsk I love you!" over and over until the cage is completely covered.
Yes, him taking a bath by himself is great! GCCs love to bathe and mine always has a big bowl for it (she likes to do it early in the morning, before her breakfast but some birds prefer to do it after). I have plastic tablecloth protectors under the cages I have in the human living areas, it protects the floor and the poop and food comes out quite easily by wiping it with a wet sponge.
Gloop: don't worry about it, he will eat everything in time (GCCs are great eaters). See if you can get some Kamut, wheat kernels and oat groats (they sell them in a 'healthy' supermarket here called Whole Foods but you can also order them online).
Bites and nips. When he gets nippy or nibbles on your clothes hard, just tell him something like 'No! Geeeently - geeeently' and touch the top of his beak with your finger so as to both indicate what you are talking about and to distract him. They like to have it caressed, too: putting your index and thumb together as if you were going to pinch something, caress both sides of his beak by moving the fingers downward from the top of the beak to the tip -it reminds them of their parents feeding them).
It's not odd at all that he looked for closeness, enjoyed it, and then bit. It's actually perfectly understandable. They are highly social animals and, to them, physical touch and closeness is not only an emotional need, it's virtually physiological. The problem he has is that although he needs and deeply desires the affection, he doesn't trust the 'givers' (humans) not to betray him (neglecting him, leaving him all on his own, keeping him caged, grabbing him) and thus the 'split personality'. Always keep a small stuffed toy handy and next time you see him going for a hand, put it in front of his beak or prevent him from reaching it by making him step up to the Tstick and, when he does, give him a reward and praise, praise, praise. The idea is to break him out of the behavior by redirecting the action to something positive and then heaping the positive reinforcement on him. I don't like to compare parrots to children often because people tend to think of them as feathered children and treat them as such when they are not, they are birds with bird needs and sexually mature at that but, sometimes, making the comparison helps people understand them better so here it goes: Think of an abused child. He wants nothing more than to have a loving mommy and daddy but, when he is adopted and finally gets loving parents, he would hit and curse them, he would squirm out of a hug and a kiss, he would try to run away, he would misbehave so severely that gives them no option but to scold him, etc. Why? Because long term neglect and/or abuse alter the normal physiological and psychological response to stimuli - even good and desired stimuli. It's kind of an avian PTSD and, although their reactions don't make sense to us because, in our minds, we are giving the bird everything he could possibly want and need, they no longer 'reason' it out the right way.
Mind you, this does not mean the bird is a lost cause or that you won't get your 'feathered baby'... it just means that it will take some time for you to have that relationship. I can see how, on a certain level, you must be a bit disappointed with the whole thing because, in truth, that awful woman tricked you into taking a little bird that has issues (created by her, I might add!) and you have every right to feel cheated but, please, think of what this means poor little Quigley! Imagine if he had ended up in somebody else's house, somebody who wanted a sweet little bird from day one and who did not want to put the time and work into 'bringing him back'... he would have ended up been passed from one uncaring hand to another and possibly living the rest of his life in a cage somewhere without love -and that is, without exaggeration, hell on earth for a little bird, especially GCCs which are so incredibly affectionate and so very needy of attention. And this is precisely one of the things you have working for you: that this is one of the most needy and affectionate species there is!
There are two things you need to keep in mind all the time when things 'go south':
- this is not his fault, he doesn't really want to be 'bad' and there is always a reason why they do bad things (aggression is not hard-wired into a parrot's brain).
- it's just a matter of time. He will, eventually, start trusting you, will bond with you and become, in every way, the little feathered baby you wanted.
