Yes. If they can not repair it at geeksquad they can show you how to use apple care. Best buy now also has best buy memberships that alows you to bring in any electronic for any store and bring it to the geeksquad at anytime.
Yes
As long as you purchased their geek squad protection plan, they should be able to help. If not they'll probably refer you to somebody who can, like Hyperion.
Best buy is an authorized apple service provider, so yes they should.
