Hi, I was planning to hike Mt. Huashan. but I am still confuse on where and how to start.

How long will it take me to reach the top as much as possible?
I want to visit and experience all the famous places and scenery up the mountain most especially the famous (but dangerous) plank walk.
I'm planning to spend at least two days to do this. I will take a cable car going down. Please help...thanks a lot!
