Some questions about using this product

So I am planing to start using this for one of my new website but have these doubts and questions before finalizing it

1) URL Structure
I see in the Permalink Setting (GeoDirectory) I can change the Listing URL Prefix is it possible to not have a slug there?? instead of
http://*******/<<your slug>>/united-states/new-york/rittenhouse-square/
i want the url to be like
http://*******/united-states/new-york/rittenhouse-square/

2) Replace “Place” and “Places” with something else
In the clowndirectory demo i see that the word “Places” is replaced by “Clown” how and where do I find that setting? I changed the Permalink name but i still see “Places”. I should be able to change that in the Breadcrumb too..

3) If I purchase the addon “Prices and Payments”?
Can it allow/disallow special custom fields for paid vs free listing. Limit number of Images etc.

4) Confusion with Categories
The listings on my website would be of a single main category just like the “Clowns” example. Similarly it may have subcategories like “Male” and “Female” so do I have to create a main category and then add the sub categories to it? or Should I just add “Male” and “Female” ?

5) Is it possible to Customize the Add Listing Page?
Say if I want to change the labels of some default fields like “Listing Title” etc where do i change it?

6) Default Location
I want it to allow me to choose any location from the United States, I entered New York as the default city and region, but now it does not allow me to choose any location outside New York, this is not what I want..
