No need for ks3.1. The differences between 3.0 and 3.1 are negligable. About the only halfway reasonable arguement for it is to make os 3.5 and 3.9 easier to install. Even they arent really necessary though and theres very little they offer vs 3.0 and 3.1 setups that have similar 3rd party enhancements.
Im currently using my phone so cant really type a long response detailing the enhancements youre trying to learn about, but theres plenty of threads around that do. If you head over to English Amiga Board (eab.abime.net) and look for a thread about making os3.x look like OS4 for example you'll find most stuff covered (its generic info though, so can be used outside of the thread starters intention).
