I'm not sure why you would need two becs, the only thing I can think of is whatever servos you're using might draw a bit more current than the ones I use.
One thing: use the eyes! Although the eyes may at first seem to be just a frivolous decoration, I find the reaction of people to the robot is far more positive with the eyes attached. Some small children will actually be afraid of the robot without the eyes, but will be attracted to it with the eyes attached.
They also do serve the useful purpose of making it obvious to everyone where the "front" of the robot is. If you don't have the magnets, just attach the eyes with glue or double sided tape.
