Novice phal owner - rotten leaf, and crack in another leaf

[katfemme89]

First of all I have to say I am in love with my new phal (little wing) and am impressed by the beauty of the blooms I have, but I am a novice, and I have noticed several things I find odd about my phal. I ignorantly took little wing out of the peat she was planted in and replanted her in some potting soil, but it looks like it has shreds of bark in it and it dries out quickly, so I don't think it should pose a problem with retaining water and causing root rot (or will it?) but anywho... I also water it every day, but I do not saturate it completely, I just spritz the leaves, and then spritz the soil until it is damp.

Now down to business: when I bought my phal, there was one leaf that had like a darker, transparent spot on it. I thought this was odd, but the leaf looked like its color was okay, so I just thought I would watch it and see what it did. well, today (about a week and a half later) I looked at the leaf and it looked like a lighter color, and had a brownish tint. I picked up the leaf to look at the underside, and it just broke off in my hand. i looked at where it broke off, and there seem to be two little bumps on the stem thing. Are these new leaves forming, or is it some kind of parasite or disease? Then, I looked at one of the "healthy" leaves, and there is a split partially down the middle. What's going on?

Now for pictures:
