If you go to the Bryce links in the Backroom there is a link to the free download of  Bryce 5.5 which I think comes with an updated presets folder which has a lot of new stuff in it. If  you want to continue using B5 instead of 5.5 and I remember correctly all I did then was move the presets folder out of B5 to documents or something and copied the presets from in my case B6.1 back in its place, I now have the same base presets in both versions.
