Answer 1

Your scope is completely empty in this line

}, { scope: '' });

If your don't request the correct permission you will not be authorized for it.

But I have to post Feeds on their wall (also I don't want the Pre-Confirmation message for the User's Approval, User should only Login into his/her account).

This makes no sense, your user needs to approve you to post to their wall. If they only login they only grant you the most basic permissions exclusive of posting to their wall.
