Actually Lucifer is Jesus, Lucifer means the Bright and Morning Star- which Jesus is. That passage is speaking sarcastically, and is often misinterpreted. It is as if I said to someone “Roll out a red carpet for to walk.” And they replied “Oh yes Queen OneFaith, would you like me to feed you grapes as well? You think you are royal, but you are no better than I.”
As for what year Satan was kicked out of heaven, I don’t know how long Adam and Eve had lived on the earth before they sinned, but Satan fell to the earth sometime between creation and Adam and Eve’s first bite of the forbidden fruit.
