Personally, I would have the PC->Arduino instructions to be able to set
target positions for the steppers, then have a synchronize/activate
command, so that you don't have a time delay between one being updated
and the next.

in code structure, probably a bunch of globals with the target position
numbers, have the main loop read the info from the pc and update the
targets as commands come in, and a timer interrupt routine which moves
the motors towards their target positions a little bit each time
around.

that would be my initial approach anyway
