Repackaging question

Hello,

I have an upstream release  umlet.zip with the given content:

        umlet.zip
        +- com.umlet.plugin
           +- <someStuff>
           +- umlet.jar
              + <.class file hierarchy>
              + src
                 + <.java file hierarchy>
(i.e. umlet.zip contains a directory com.umlet.plugin which contains a
umlet.jar file which in turn contains the java source and binary class
files)
        
My intention is, to repackage it to:

        umlet_version.orig.tar.gz
        +- umlet
           +- <someStuff>
           +- src
              + <.java file hierarchy>

Does this sound OK? 
Should I refrain from renaming the toplevel directory from
com.umlet.plugin to umlet?
Does the package need an additional name tag to the orig filename?

Thanks

Ben
