Help: PyObject* questions

Nope. "Carbon copy" could mean any number of things. From 
incrementing the ref count to doing a (careful) deep copy. A PyObject 
may be self-contained, or the struct may have pointers to allocated 
memory. All the same decisions you'd have to make in creating a copy 
constructor in C++, but without any help from the language.

Yup. All the high level API calls are well behaved this way.
