-keep your vision up.  That will smooth things out, give you time to prepare for the rhythm of the upcoming moguls, and because you are not looking down at the speeding ground, you will feel like you are moving slower, at a more manageable speed.
-keep your feet back underneath you.  Many people push their feet out in front of them after absorbing the mogul.  Push them down, not forward and keep the pressure on the front of your shin against the boot, keeping pressure on the front of the ski, so that edging actually works.
-keep your hips forward.  Try to feel like your hips are leading down the moguls.  That will help keep you out of the backseat, and in a position to turn quickly.
-keep your hands out front like they're holding an imaginary steering wheel, driving you down the mogul line.
-try to be as smooth as possible.  Make it look easy.  you can always be smoother
-all moguls are different.  no two lines are alike, you have to be able to adapt constantly to changing conditions and contours.  Being adaptable goes hand in hand with being a good mogul skier.  Different tactics work on different moguls.  Like a big wall of a mogul, you might want to drive your skis into it halfway up the face of it instead of pressing your tips all the way down into the rut and then trying to absorb a 4' mogul that you can't physically absorb.... and so on.  Rip it!
