1. No, it is mailed

They will wonder if there is a reason why you did not marry earlier and add your wife directly to your application. I heard of one person who had to prove that he did not live with his fiance for 12 or more months before immigrating. If they had, they would have qualified as a common law couple and if they had, he would have had to apply for her immigration at the same time as he applied for his own.
