My Phalaenopsis needs your help!

[punkrockmom]

Bit of back ground: I bought this orchid at work a couple years back and kept it indoors till it pretty much looked like it was a goner.. Dont know what I did wrong back then but it was several years ago and the pot stayed outside for a long while and then my parents grabbed the pot for some of their plants and before they potted anything noticed growth and left it to emerge(see Photo) now I would love to know what to do with it to keep it healty this time, do I pull those husk like things back? Can I repot the small green growth towards the bottom, should I trim that stalk at the top? (see photos) I recieved anouther for mothers day which is healthy right now and hopefully I can keep it that way ANY suggestions would be awesome!!
