Hello and welcome to the forum! Please don't apologize! Your post is not long! You should read some of mine sometime! lol So, you are fine. Don't worry about it. A lot of times, the more you tell us, the easier it helps us to answer your questions! So no worries, okay? Lovely to have you and Puck join our flock! 
Oh, yes! Regurgitation and biting are classic signs of hormonal behaviors. There are things you can do. One is to ensure that Puck is getting at least 12 hours of darkness every night. I would suggest you even give him an extra hour or two of sleep every night until the hormonal behavior has stopped. It tricks them into believing it is wintertime and not a good time to reproduce. The other thing is to watch his diet. Avoid foods that are high in fat, carbs and calories. No human snacks. These will trigger your bird into thinking that food is in abundance, and it is a good time to have baby birdies. Stick to good quality seeds, veggies and leafy greens. Give fruit and nuts occasionally during this time. Cut back on the protein too. Avoid soft foods like oatmeal. They are too much like regurgitated food a mate would give him.
If you can, distract Puck by getting him to exercise. Encourage him to fly – it is really good for burning off all that excess energy he is experiencing right now. Maybe provide him a foraging toy, or anything you can think of to keep him occupied. You can also try some target/clicker training, if he is up to it.
It is also best to ease off on the cuddling and scritches during hormonal periods, and no inappropriate touching below the neck. You do not want Puck thinking that you want to be his mate.
That is a shame Puck scrapped his head on the ceiling. Poor little guy. We are not experts on this forum, but if it were me and he seemed fine, then I would just keep an eye on it. The feathers should grow back in time, if they don’t, then you may want to check with your vet. Do not use Vaseline. If Puck ingests it, it can make him sick. And you don’t want Vaseline getting on his feathers.
Hormonal periods are hard on our birds and us. Hopefully, he snaps out of it soon. Let us know how he is doing. Hope he starts feeling better soon!
