What I did for my styles is there are some I like from a set and some I don't so I opened up all the sets that have the styles I like and then deleted all the ones I never use from the sets. Then I resaved all the ones I like the most as Favorite-dropshadow, Favorite-bevel, etc. That way I don't have to keep a bunch of stuff I never use on there!! Same with action sets, for example I divided up all my AC actions into groups (woods, paper tears, glass/plastic, etc) and then created new set with them all labelled. That way if I am going to want a glass action I don't have to load them all individually and I don't have to keep them on there if I'm not using them anymore!!
