The following will show Vertices from Mysubclass only:
select from Mysubclass

The following will show Vertices from Person and all subclasses of 
Mysubclass.
select from Person

In either query result, you will see all of the properties of each vertex.  
Class inheritance will inherit defined properties but it doesn't sound like 
you have actually defined any properties (just added property values to 
vertices).

For this you need to use the "create property" SQL command.  You can 
execute it from the Java API but there isn't a method in the API such as 
graph.createProperty(String vclass,String propertyName, etc.).  See the 
following for more details:
