I feel relieved (and amazed) that I seem to have got so relatively little wrong :-) . (Not little, just relatively little. Or was that realtivitly little). >> It is easy to plot classical energy of a particle (or starship or >> ...) > What formula do you use for this plot?

Energy from classical velocity and mass. Mass from rest mass and velocity using special theory. Plot energy against velocity. Voila!. Takes almost no time to do - try it, you'll like it. You'll also probably explain why it's meaningless in any useful frame of reference ;-) -but that would ruin a good story.
