Assuming you're trying to develop plugins, i.e., that your Java projects
are plugin projects, you'd not modify the build path directly but rather
modify the MANIFEST.MF using the Dependencies tab.

No, you don't need to import the SDK, just make your plugin depend on
the specific plugins you need.

Such jars need to be bundled into a plugin as well. I.e., put them in a
plugin project and via the Runtime tab, specify the locations of those
jars within the project.

Read a little bit about the PDE (Plugin Development Environment).
