Hi Robby!
I was in Lowe's myself a few days ago and I think I saw some Phals in the same "cube" pot you refer to. It is all-glass with no drainage holes, right? You need to get it out of this container as soon as possible...any pot with drainage holes will do. That glass cube is a Phal death trap!
It's hard to say what kind of bug you saw...I wouldn't worry about it unless you see more than one, along with plant damage (chewed leaves, etc). Tap water will be fine...but as your plant is in what must be a soaking wet media at this point, you will not need to water for a while (repot it into a regular pot first, and then water after the media is almost totally dry).
Regarding the wilted flower, it is not likely to "perk up." Phalaenopsis flowers will wilt naturally as they age, and the change of environment caused by bringing your plant home may have played a part (as well as heat from the tv). Your best bet is to enjoy the remaining flowers and hope for more blooms as the spike continues to grow.
BTW the full name of your orchid is Phalaenopsis Memoria Cecilia Rimland. You should keep the tag bearing that name with your plant. Many of us have purchased Phals with no tags, or have lost track of the names over time...I can tell you that it's frustrating to not be able to identify your plant once this happens!
