Answer 1

What you can do definitely is use "Where used filter". It will return you all items that use your component (which includes your component). Then you can filter it via tcm id to get just local copies. For more information how to use GetUsingItems filter check this blog.

I think that you can also use BluePrintChainFilter with BluePrintChainDirection.Down property, where you will need to filter all localized components.

Hope this helps :)
