Phal Advice Needed

[Sweet_Piece_Of_Work]

Okay...My plant is a pretty good size white phal with fairly large blooms. That is, when it had blooms. Which brings me to one of my reasonings for joining the forum....my worries about the care i give my current orchid. I hope to eventually obtain several different species, but first i have to care for this one and i need some advice. So here is my story. First off this is my very first orchid and it was gifted to me about 3 or 4 months ago with 3 spikes and about 5 or 6 blooms on it. As soon as i got it i immediately began to research the orchid and its care and began to follow most of the advice given on the net. After a few weeks a couple of the blooms fell off, which i expected, but it also budded and bloomed about 3 more blooms after losing those few. Eventually over the next 4 or 5 weeks all of the blooms had fallen off. About a week or so after the blooms fell off one of the spikes turned a weird yellowish brown color and dried up. I eventually ended up cutting that spike down to the very bottom of the plant. My first question is was this a mistake or did i do the right thing? I also wanted to know if i did the right thing by trimming the other 2 spikes down to where the first blooms were? I trimmed the other 2 spikes because they too were turning color and i wanted to stop it before it destroyed the entire spike. One spike is fine now and the other I don't know about yet. If it continues to turn color and dry up what should i do then? Trim it again?...I then noticed that the plant had alot of roots coming out the little plastic pot filled with moss so after reading up on it a bit i re-potted the plant in a clay pot with proper bark and trimmed off all the dead roots. Was this a good thing to do? Or could i have harmed it? Its been about 13 days since the re-potting and now one leaf has turned completely yellow and another looks as though it is turning to. What does this mean? Also are they suppose to droop over the pot or stand out? The color of the other leaves are a bright green color, which they have always been, and some of the leaves have this dark color on they're bottoms. Is this a fungus or disease? I also wanted to say that I mist this plant 3 or 4 times a week lightly in the morning and in the afternoon. I water about once every 7-10 days and have only used fertilizer once after getting it. I also try to keep a tray of rocks with water in it under the pot. Should i not do that? The temp in my house stays between 75-85 degrees all the time and my plant sits facing a south window with a sheer curtain over it.Since re-potting though it has only been watered once and is in a dark spot away from direct light. I've uploaded pics of my plant so that you can see what all I'm talking about. Three of them are of the last bloom and the others are the plant in its current state. Sorry for the long post and the carrying on and on but I'm only trying to be as accurate as possible in describing it all to you so i can hopefully become successful at caring for orchids.
