too many settings?

[Bill McGonigle]

I'm getting confused among the many different ways to configure some
settings with KDE on Fedora.  I'll illustrate with a specific, but
wonder about the general solution.

For display power management, I have, at least:

Launcher...
 Administration...
  Display (which has no power settings)
 Settings...
  Screen Saver (which has a Display Power Management area)
 Settings...
  System Settings...
   Display...
    Power Control (with different settings/values)
   Advanced...
    Power Management...
      General Settings...
        Let PowerDevil manage screen powersaving (I think this implies
'Edit Profiles' will have precedence, but only a poweruser could
interpret the help to know that, if I even got it right)
      Edit Profiles...
        [Profile name]...
          Screen (which has even different time values)

Volume controls would be another one - I need at least KMix and the
Pulse Audio control panel, which doesn't even show up in my menu.

So, in a situation, how do I figure out what to use?  Is there a general
rule of precedence or do I have to understand the interworkings of the
parts to know what to set?

That aside, do I have my systems installed incorrectly?  If not, is
there an existing effort to refactor redundant/confusing settings GUI's?

Thanks,
-Bill
