Adobe Illustrator CS2 tip. Moving towards center?

I was wondering how to do this. Say I have a circle of 20 circles. In between each circle is about 1/4 of an inch of space. I would like to move all the circles toward the center until all circles touch. At one time preferably.
I have tried replacing the spine; some overlap, some gap, none can be moved independently.
I have tried brush stroke of circles; none move independently and some overlap at some point.
If you have tips for what I have tried or something new completely, please let me know.
Thank you in advance.

I have tons of brushes for Illustrator & Photoshop CS4. Are there any visual apps to keep them organized?

I would like to be able to use it to view them without having to load each brush set to see what they are. So basically either a plug in or an external app that will organize them.
