A number of tapes could work. New Behavior Generator to acquire behaviors, Anxiety-Free to project strength, Belief for belief in your own ability, Prosperity, New Option Generator, and Instantaneous Personal Magnetism. There is no "right" way. Play with them and see which combination works best for you.

As far as modeling comedians, TV people, etc? Absolutely. Use Instantaneous Personal Magnetism or New Behavior Generator. It is best to use the tape within a couple hours of seeing someone, whether in person or on the big screen.
