Route Advice, Luggage Storage, Coat Rental

Hello!
I am currently on my way to Huashan by train from Huangshan via Hefei.

I will be arriving tomorrow afternoon. My plan is to hike all the peaks, stay overnight, and then catch sunrise at East Peak and then head down.

Questions:
1. What is the best route to hike up and down (no cable cars) all the peaks except East Peak from an afternoon start to end and sleep at East Peak?

2. Where can I store my luggage? Does the park itself have multiday storage? Or do I have to store it at the train station?

3. If I choose to camp, are there spots of flat ground that are easy to find? I camped two nights in Huangshan and it was difficult to find.

4. How steep are the paths in comparison to Huangshan? I wanted to see how feasible it is to carry my camping gear with me. I know it will be more difficult but I'm always up for a challenge.

5. Is the plank walk a big circle or is it from one end to another end? Thinking about if I have to carry my big bag across the planks...

6. How much are the heavy coats for rental? Where will one rent them? If you rent them for overnighting at East Peak, will that mean you have to carry it around for the other peaks?

7. Are there shelters near East Peak for overnighting under in case of rain?

8. Will the plank walk still be open in the rain or what conditions might close it? Because I am definitely going to the mountain for that.

Thanks! I want to figure out a way to do this trip as cheaply and efficiently as possible.
