How to get the jars should be obvious now isn't it? There is a link to the maven repo... DB changes from 3.1.x to 3.3 are not documented afaik. From 3.2 to 3.3, you can try to run jBPM once with the hibernate config set to create-or-update (try on a non relevant machine first). Maybe that works for 3.1 as well.
