Folks solved the Drupal problem myself, was not getting too much support from WebForm-Commerce team. Lots of time playing with the Admin module and 'Content' and 'Store' menus. (Why not color code these sections with different shaded bacgrounds, easy navigation, all look the same..)
Structure-->Contnent types->Webform-->Manager Fields --> add 'Product reference' field type {Need to tweek Manage Display also}

Moved on to D7 Commerce WebForm as solution. Was not looking to activate so many new modules, but had to do it for mainstream support.
Thanks #28 adrianolmedo, the manual script update described allowed to get my site backup.
I was also working on installing/activating Commerce module and its related modules/features. Initially I built a Commerce-WebForm form on my local host. Next step was to build it on the shared hosting site, then the errors appeared. Happy to get my hosted site backup and plan next steps.
