All you have to do is select all the objects, and create a new group (as the group's material will override the materials of its members). With the group still selected, give it a new material (doesn't matter if it is phong, lambert, etc). Then open the render tree (7) for the group, and bring in an ambient occlusion node (Nodes> Illumination>Ambient Occlusion), and connect it to the material's surface.
You can adjust the AO node's properties from there (increasing the samples is recommended for a much smoother look, but otherwise I left the colors and the spread at their default values - you can play around with those if you want to control the look a bit more).
An an example with different spread/distance values:

I know this is going to sound crude, but how have you actually managed to get that to work? I tried following your tutorial, and I got a final product that looked nothing like that! The final render looked had only minor differences between itself and the product pre rendering. Have you got a light in there or something, because I'm just not getting that sweet and smooth result.
