Phal - last two leaves dying?

[Rosiefuture]

Hi folks,
This is one of my noid phal rescues, it's been doing really well and blooming for about 4 months. A couple of days ago the last bloom dropped so I trimmed the stem back to just above the top node. The plant has two leaves, one is about 6 inches long and the other is 10 inches long. I then noticed that the shorter leaf was going red/yellow at the crown. From the pics I've taken today you can clearly see that the leaf is dying. What I'm wondering is:

• Should I cut the dying leaf off?
• The larger leaf is quite red at the crown, is it likely to die too?
• Should I cut the spike off completely?
• If the larger leaf does die, is the plant likely to throw a basal keiki?

I took the plant out of it's pot and there were a couple of rotted roots which I snipped off but on the whole the roots were really good.
