Running PPT 2003 SP-3

I am creating a custom slide-show for some non-techy staff here.  I would
like to predefine the style for a column, bar and line chart for them.  (I
could just try to create three separate sheets with a version of each, but
that seems to be not quite as professional)  I used to know how to do this,
but in rummaging around inside PPT's help, I can't figure it out!  (sidenote:
I can't figure much out with PPT's help, I seem to always end up here)

I have 3 different masters set-up (no guarantee I did that right either) one
for the title slide, regular slide, and a "section break" style slide.  (I
know enough that I did create them correctly all in the master view, but am
uncertain as to how to make it obvious to the end-user where to find the
section break style slide)

Any help would be greatly appreciated!!
