As Danny said, start red Konis on the softest setting, find the tire pressures you like and if/when you notice handling getting a little sloppy adjust up a notch. Koni used to have the reputation of being uncomfortable on the street because too many people (especially VW owners) in the past made the mistake of thinking they needed to automatically be made stiffer right from the start.
Some people say that the only thing better is a set of custom valved Bilsteins (most are set up for offroad and are way too stiff for a street car with a Beetle's or Speedster's weight). There apparently is a shop down in CA (or Arizona or Nevada) that someone on the Samba (or maybe it was Shop Talk Forums?) said could rebuild them with custom valving but I never got the name out of him.
