Wow! Great walkthrough.
Just a couple of comments
Firstly, in the T junction room, there's a little bomb insect. You can use it to blow up the rocks at the back before you light the torches. I think there are some Rupees there.
If you've already lit the torches and the platform is raised, you can put one out with the boomerang and the platform will go back down, allowing you access to the boulders.
Also, in the room near the end, where you give two options, if you follow path 1, you can jump over the gap to get the chest after rescuing the monkey. It's a lot easier to jump in that direction.
