Some sources say gongfu is only for oolong, some say it's suitable for pu-erh and greens as well. Being new to gongfu myself I've not even had green or pu-erh tea gongfu.
Personally, I prepare my oolongs in yixing pots and greens in anything glazed or glass. I use a teeli strainer for my greens as well. Pu-erh I usually prepare in a large insulated mug and don't remove the leaves. This is dark pu-erh, I haven't figured out what to do with my green pu-erh yet
There were one more thing that puzzled me: in this tea house they used

I do temperatures close to textbook. Any time I've actually boiled the water for green tea preparation I've ended up with bitter tea.
Hope this helps,
