Quaker Parrot is pulling his feathers!

Well Paco is at it again only more serious this time with his feather pulling. He's over ten years old and never been mated.

1)Is he too old for a friend to be introduced and would it have to be a female?
2)He's very territorial about his cage so if I did get another Quaker would it probably be a good thing to start them both in a new cage together?
3)Would another Quaker bring him out of his shell, he has stopped talking with most of his phrases? He's frustrated I think so I let him listen to music and have a couple of VD's with bird song and Rainforest sounds.
4)Any other hints for me on the feather stripping? Oh he does under his wings, a tad on top of them and has his front totally plucked which makes him look just awful.

He is not interactive other than running up to and nesting on my shoulder in my hair. He does respond well when I give him showers and hair dryer him dry very carefully-gun shooting away from him and he gets the rebound warm air from the sides.

I'm sorry about the questions not being more organized and there being so many. I will sincerely appreciate any hints and advice you can offer!
