I need help further breaking down the scenario given for an estate law assignment. Is there anyone who may be able to help talk me though the question below?

A client walks into your supervising attorney's office. His name is Mr. Barry Rich. In the initial interview he tells you that he works as a commercial real estate developer. He is concerned about being sued since his occupation is one of high risk and he has assets of approximately 5.5 million dollars.

Mr. Barry Rich is married to a woman who is a citizen of Japan. He is 55 years old and has three children and one grandchild. His assets consist of a house worth $500,000, oil and gas royalty rights in Oklahoma worth 1.3 million dollars, stocks and bonds worth 2 million dollars with a tax basis of $50,000, and 2 million dollars cash value in various life insurance policies.

I need to discuss what steps, I believe Mr. Rich should take to avoid federal and state estate taxes and to provide some protection from lawsuits. What additional information should you know to help Mr. Rich achieve his objectives?

I am completely stuck.
