   1. I had to also add the 2.9.1 scala library by choosing Add External Jar and choosing that library

You should be able to run unit tests or the kafka server or other command line apps through eclipse for debugging. To do this right-click the class you want to run and select

1. 1. Run as...<Unit Test|Scala Application>
