Repotting rescue phal orchid?

[Acwilliams]

So I have an orchid I rescued From the hardware store. It was 2 dollars and I couldn't pass it up. I got it home and watered it. I believe it to be a phal however I am not sure as I am new to orchids. It's leaves do look similar to another phal I have though so I'm sure this is what it is. When I was inspecting it I noticed it was tightly packed in moss and several roots were broken some were rotten and the spike was long dead. I cut the spike immediately, but the fact that it was in that moss didn't rest well with me. I went out and purchased some miracle grow coarse mix bark and repotted it in that, and cleared out all of the bad roots. I guess the information I am looking for was is this the right way to go about doing this? And secondly does this plant look healthy to everyone before and after?
