This component can be used across multiple sites once purchased?

Hello everyone I am a new user
My intent is to build a site that provides reservation services for accommodation, such as b & b, holiday homes, yachts, cars and car hire, tourist routes in my area, this component seems quite complete.
I was wondering:
-There is an Italian translation of the backend?
-Once you've purchased the product must be renewed every year or is it unlimited?
-Can be used in multiple sites?
-The component can be used for tourist routes and yachts?
-What is the difference between BOOK IT! 2 PRO and BOOK IT! 2 PAID?
-there is a form of filtering about service offered by my site?
Contains a component-seo-sef inside? Or not necessiary? Or do I have to add jomsef for better ranking?
Many thanks and sorry for my english!
best regards
