In Attributes Controller, select the product and then select the option name and an option value, and enter the price for it with a prefix of blank, not +. You can enter the weight, again without a + since it is the total for the product with this attribute.
You are correct that you give the base product a price of 0.
There is not an efficient way to give the attributes "part numbers" in the way you are asking; but what you show is not a unique part number for each attribute, just the product name/number with a weight suffix. That will come through very legibly in the order. This leads into...
Make one generic product with all the attributes set up. Then, if the products themselves are very similar, copy/duplicate the product 19 times and edit each of those with the name, description, prices etc.
If the products are too different for that to be efficient, make all 20 products, and then click on "Copy to Category" near the top of Attributes Controller for the first product, and copy the attributes to all the rest.
You will need to edit the prices for each one, but it's still a lot easier than entering from scratch.
