AutoCad :: Script Using Design Center?

I have never written a script but I figure this task is a good place to start. We currently have almost 8,000 files that all use different dimension styles, leader styles, layers and layouts. (All before I got here) I have successfully used the design center to where we can open an old drawing then go through and add all of the new 'standard styles, layouts, and layers'

can I write a script that will add all of these at once. It is not that it is that terrible of a job to do, but like I said my thought is it will be a good way to learn more about scripts, and we have a lot of drawings this needs to happen with.
