Sorry, I expressed myself in an unclear way. I asked you to import the helpers to debug your problem. Do the helpers move when the bones are moved? If not, that would explain why the clothes don't move.
The helpers are used by the exporters, both mhx and collada. Clothes inherit vertex groups from the base mesh, including helpers. Once the clothes have got their vertex groups, the helpers are not needed anymore and can be discarded. This happens at export time for collada and at import time for mhx. But if a helper does not have vertex groups for some rig, any clothing associated with that helper will not move.
So, import the character with or without helpers. That does not affect how the clothes behave in Blender.
Anyway, the main question is: do the clothes move in Blender? If not, there is something wrong with the MH-Blender pipeline, and it is our problem. If they do move in Blender, the problem has to do with export from Blender.
