Repeating Effects in Photoshop (CS)

I just finished making an icon with multiple layers and actions (such as duplicating, changing transparency, blend mode, etc etc), and I'd like to apply this effect to an entire batch of icons that I'm making. Is there any way to save the history of a document and apply it to another, or copy each separate layer in one giant group to paste on another image?

I'm using Photoshop CS.
