Buy this book. It's worth it.
Moishe Rosen, founder of Jews for Jesus, and his wife, Ceil, have penned a very helpful book that focuses on Jesus Christ as the fulfillment of the Passover celebration in general and the Passover meal in particular.
Christ in the Passover has helped me a great deal because, as a Gentile, I have only a very basic understanding of the Passover meal. It was amazing for me to read this text and have the Passover come alive.
Rosen does an excellent job in describing both the elements and order of the meal, and also the meaning behind the meal. He shows the immediate meaning as it relates to the passover just prior to the exodus. Rosen also describes in detail how Jesus fulfills the various aspects of the meal.
In particular, I enjoyed and benefited from the author's discussion of the aphikomen. This is the three pieces of unleavened bread that symbolize (whether most Jews recognize this or not) the Trinity. Amazingly, the second piece of bread is broken, hidden, and then found by the children of the family. This is clearly symbolic of Jesus' crucifixion, burial, and resurrection.
If you want a greater understanding of the Passover as it relates to Christ, buy this book.
