What IP address is provided to my customers and termination partners?

The virtual node IP address, since it is the center of all communication. The customer (originator) and the carrier (terminating party) see only the PortaSIP virtual IP address.

Yes, the Limit Controller component in PortaSIP allows the enforcement of so many calls per second. With this functionality you can decide upon and restrict the number of dialing attempts that can be made by an endpoint (e.g., a call center PBX) per second.
For more information, please refer to the Traffic density control section.
