Arc will let you pretty much click through (Next > Next > Next) and come up with a legend that is right for the data frame.

The arrow keys let you move layer names from one pane to another. Arrange it so that the Legend Items pane has only some_lines and some_polygons in it, as in Figure 3-7. Set the number of columns to 2. Finish the wizard. Drag the new legend to the ALL data frame.
