Hi,
A.1 It depends what you want to do...
A.2 Throughout our forum. Again for a precise answer, we need to know what you want to do.
A.3 Too many categories ? Well, I don't recommand having more than a few thousands categories. For several reasons, but the main ones are:
- it would slow down the processing of the pages
- having too main categories, the customers will have a hard time to go through them
B HikaShop is not compatible with the smartsearch system of Joomla. So you can use it, but it won't interact with HikaShop.
It's better to use the normal Joomla search system, or the HikaShop filter system.
HikaShop has a HikaShop products search plugin that you can configure via the Joomla plugins manager for the Joomla search system. And you'll find many search modules for Joomla compatible with the Joomla search system.
You can read more about the HikaShop filter system here:

C. You can use the filter system of HikaShop. You can have 2 ranges on two custom product fields with filters of the type "cursor".
The filtering requires a refresh of the page, so it's not "ajax", but that's the same on your example...
