Answer 1

You can inject the currently active MPart in your execute method using the IServiceConstants.ACTIVE_PART name. The getObject() method of MPart returns your part class:

@Execute
public void execute(@Named(IServiceConstants.ACTIVE_PART) MPart mpart)
{
  PartStackOverflow part = (PartStackOverflow)mpart.getObject();

  ... call methods
}

Alternatively use the find method of EModelService to find your part by its id.
