That is all the documentation for what WAS core to LiteStep. Since then all of the modules were ripped out of the core distribution. Beyond that information you have documents that come with each and every module that tell you how to manipulate it. I learned how to do everything I know with LiteStep through trial and error and the deconstruction and manipulation of others themes. There really isn't much out there that goes into ultra high level configurations. You can check out some of the things in the Code section of the forums, there are some good snipits in there from time to time. Basic rule of thumb though is don't make it more complicated than it already is. LS is a big puzzle where you control the finished picture.
