Yes, it's for statically linked extensions.

|2. What's the difference between funcall2 and funcall3?

funcall3() does not invoke private methods.

|3. Is Struct still used, or is it deprecated?  If it's still used, how is 
|it different from Data (Data_Wrap_Struct, etc.)

It's still used.  Struct class is for bundling Ruby data.  Data is a
wrapper for "C" struct.
