To be clear, OpenStudio (the application) can do all these analyses, yes. OpenStudio (the SketchUp plugin) can be used to create your building model geometry from scratch, and also can create and apply many of the elements of the energy model (constructions, schedules, etc.), but the OpenStudio application is the main place for getting things done. Through the app, you can apply report measures to get your LEED calc info; the other items you list are all just part of EnergyPlus' core capability.
