I got a beautiful Phal for mothers day, and it is my very first Orchid ever. I want to make sure that I am taking the best care of it that I can. I have been reading what I need to know on the "Orchid Basics" and it seems as though the color on the leaves of my plants isn't best, but I am not sure exactly whats wrong with it, so I figured I would get on here and post some pictures and see if anyone has any feedback.
The picture of the leaf with the dark spot and yellow around it:
I am just trying to figure out if this is the beginning of black rot, and if it is what I can do to take care of it.
The picture with the grayish, silvery spots:
This is from the bottom of the largest leaf, it isn't on any other leafs. What does this seem like and what can I do to help this?
The picture with the shriveled up grayish finger things (I really have no idea what they are

:
I'm not sure what they are, at all, but I am uncertain what to do with them. They are not aesthetically pleasing AT ALL, and if they are unnecessary I would rather them just not be there, any suggestions?
And last but not least, the picture of the pot:
I just want to make sure that this is a sufficient pot for the plant. It came with moss as it's media and it also has moss on the top right under the leaves, should that be removed to help prevent root rot?
I added the picture of the flowers just so you can make sure that it looks like it's supposed too. Like I said, I am a SUPER beginner, I don't have plants that I don't usually accidentally kill, but this one is special and I want to make sure that's not the end result for this pretty little thing!
