The "most obvious" way to pass complex C++ data to perl is to use objects with accessors with a complementary perl XS mapping (so you're using a pointer to a C++ object like a perl object). You want the accessors because although perl can in theory access the data in a foreign object directly, it gets messy very quickly. IIRC in C++ structs are more or less the same as classes so you should be able to transform your structs into classes reasonably easily.

In C++ 

class SomeObject {
  public:
  int get_valueA();
  void set_valueA(int value);
// etc...
}

XS code (you need these to use the methods from SomeObject in perl: 
int
SomeObject::get_valueA()

void
SomeObject::set_valueA(int value)

You'll also want to set up a typemap for each class. See also the standard typemap file in your perl distribution for T_PTROBJ_SPECIAL.
