RE: Four-Star
TNRabbit is right about talking to the instructor first. He may have a lot to suggest or he may insist on your trainer. A good instructor will get you thru your training and be there to help as you move up to other planes like the 4 Star and Mustang. I think that I could be flying for the next 10 years and my instructor would still be interested in what I'm doing.
Also, I also agree that you are showing excellent judgement in asking about these things first. You sound like you are going to do just fine.
