Variants - Set default value and product display

Good day,

I have two questions:

1. How do I change the default value from unlimited to 0 for the variants found in my characteristic Ring Size? Typically they will have 2-3 sizes in stock, so it would be easier for them to add new products to their site if all of the ring size variants were set to 0 as the quantity instead of the default which is unlimited.

2. The ring quantity is set to "unlimited" so the characteristic "Ring Size" controls the inventory. However, when all ring sizes sell out in a particular ring it still shows up in the list of available rings on the front-end. Is there a little line of PHP that I could add that would say something like "Any products in the category of "Rings" that have no variant quantities in stock under characteristics "Ring Size" do not display"? An example of a ring that sold out but is still showing can be seen here: screencast.com/t/beklXm65H - I get this message: Ring Size No values found. Instead, I'd rather the ring not show up as available. I do have "Display out of stock products" toggled to "no"

Thanks,

Dawn

Brilliant! It worked perfectly.

Note for other readers. For answer #1, Nicolas recommends to edit the column "Product Quantity", here is a screenshot of where to do that in PHPMyAdmin:
