To firstly prepare a speech you should select what you´re going to talk about, what you want the audience to feel about it and how you are going to transmit the message.
Once you determine the purpose of your speech you must gather information to support your posture and with the information, you have to select an appropriate topic. Finally before delivered it to an audience you must practice to be familiar with the topics and the organization of the speech.
That statement is true. In the farewell speech, queen elizabeth use the word I to describe the main character point of view, which is a sign of first-person point of view. Hope this helps
