From my experience, the above description is exactly what you need to do to conduct a city orbit.
The Yarra CTAF is for helicopters (unless you have a super-dooper stoll aircraft) so no need to worry about them and yes, class C is from the ground-up, so 1,500 or 2,000 is essentially irrelevant to you, just do what you are told.
You might sometimes hear "clockwise orbit" rather than "Right-hand" - but both work.
Feel free to PM me with any queries about the local area and I can happily assist you.
Enjoy.
