A new hope
If you are a mac user who has never tried scripting, I really recommend having a look at AppleScript. It is a great language to learn, due to the fact it is written almost in plain English. There are lots of books on AppleScript out there but one of the best is AppleScript 123 by Sal Soghoin and Bill Cheeseman. There is no InDesign content, but it is a fantastic beginners book and will give you more than enough to get started.
If you don't fancy splashing out on a text book, you can pick up plenty of tips and tricks from http://macscripter.net/. The community is very friendly and always willing to offer help and suggestions when your newly written all encompassing awesome script doesn't compile or does something weird. Which happens. A lot.
