there is spline animation to get objects and cameras alike to move in
smooth curves.  there is a macro by chris colefax made just for this
purpose.

 i think you meant <= 1 in that first part.  what i would do is just use
two cameras.  but you could also define a variable, CamPosition, and
then update that with clock (instead of changing the camera itself) and
put this variable in the camera's location.  then, you'd already have
the info you need for the second part in that same variable.
