Answer 1

There is nothing stopping you from deleting a Keyword that is only used in old versions of other items. You are only prevented from deleting it if current versions refer to it.

So the real answer is to just call the Delete method.

That said, if you want to use the Core Service to find out the items that are using your Keyword, you need to use one of the list-related methods (e.g. GetList) and pass in a UsingItemsFilterData object as the filter.
