Answer 1

I would define a target definition for your Eclipse distribution. Include all the features (including source) in the definition. Then you can use you importer to import plugins from your target definition into your workspace with sources and work from that. Having target definition is easier because you can change your setup on-demand.

Edit: Forgot to mention that in import wizard (File -> Import -> Plug-in Development -> Plug-ins and Fragments) make sure you select "Project with source folders" under "Import as". Otherwise class files will be imported as jars and not deflated into your project. Just makes it easier to work with them this way.
