Rony:
Alright, Over 85 views, still no answer.
Anyway, I just went ahead and added almost 485 option values to the "products_options_values" table using SQL Script. Then used Apsona's shopadmin to link products to attributes (option values).
I also had to set the "Sort Order", because products are priced by attributes, and I want to show the prices in ascending order. This is very important, otherwise, I think the attributes will show up in a random order.
Here is a screenshot after I uploaded my values. As you can see, My SKUs were based on attributes.

Here is a screenshot of one of the pages with attributes that I uploaded....

So far so good ..... :smile:
Hope my experience with bulk option values uploading helps someone else.
Option VALUES are associated with their Option NAMES in the database via a complex relational cross-reference, governed in products_options_values_to_products_options. I trust you remembered to assimilate all the Option NAME ID's with their corresponding Option VALUE ID's, and that you wrote the relevant data to this table as well?
Below (and sorry about the length) is one of MY database's relatively simple relational data
(`products_options_values_to_products_options_id`, `products_options_id`, `products_options_values_id`) VALUES
