Your Phal actually looks quite healthy. You have to remember that these plants have been travelling and have been stored not always under ideal conditions. Most of them experience major stress.
It is normal for the bottom leaves to eventually turn yellow and brown and then fall off. Otherwise the leaves look fine. I checked the St. Augustine Fl. Orchid society for the spotting and they did not list it.
http://www.stauorchidsociety.org is a valuable resource for orchid growers, especially new ones. You did not say if it is a "just add Ice" orchid. Home Depot sells them here in the States and folks promtly kill them over time by freezing them to death. The crack in the center of the leaf is nothing to worry about and neither is the bit of black on the side. Remember they travel in close quarters and if it was on the discount rack it probably has been handled a lot. Give it some time to feel at home and it will surely perk up. One last caution thou, never let water stand in the crown, if some should get in there while you water or mist, soak it out with the tip of a piece of paper towel. So best of luck to you and your pretty orchid, she shure has beautiful flowers.
