It's true that there's no ideal location for the "distance" parameter. I hadn't thought of defining it in the property itself; I don't think that's a good idea, though, because it's conceivable to have different queries that check for different distances for the same property.

And to clarify, the '::~' comparator can only be used for specific coordinate values, not a string that can be geocoded like "Paris". And to actually find all points that are, say, "5 km from Paris" is unfortunately well beyond the current capabilities of SMW. :) It may be something that Semantic Maps will be able to handle in the not-too-distant future, using various third-party tools, but probably not through the #ask mechanism.

Yes, although the current syntax does not really have a good place for setting
something like this. Another option would be to have it in the
datatype/property. In any case "close to Eiffel Tower" usually means something
else than "close to Paris" or "close to France".
