I don't agree with the common and often repeated opinion that birds get overgrown beaks from not having things to chew. In my personal experience, this never, ever, ever happens. It's always either liver malfunction or a deformation (if the top beak doesn't align as it should with the bottom beak, either one or both don't 'wear out' properly and grow too much). But, I went back and looked at the videos and, although it's dark and not very clear, it doesn't look as if he has an overgrown beak to me. Peely, ragged edges, etc are from a bad diet and all of these problems will disappear in time (but don't get impatient because it will take close to two years).
Nails and how short or long they should be are more a matter of personal preference. I hardly ever trim any nails. I do it to the canaries and to the two liver damaged parrots once a year and, on occasion, to the cockatoo because his nails are like large and sharp as daggers and he has this habit of grabbing my face with his foot (it's his way of 'hugging' me) while we do the 'pa pa pa' he loves so much.
