See http://wiki.eclipse.org/RCP for a description of RCP apps. They usually use the Workbench and provided services (preferences, new/import/export wizards, help, the editor and view part concepts, etc).
Eclipse 4 provides a modeled workbench and Dependency Injection based instantiation of contributions, and can be used to create Eclipse applications with less cruft than the entire Workbench. By default CSS is used for styling.
Eclipse 4.2 is the RCP Workbench with parts of the presentation re-implemented in terms of the model.
