First, Welcome!
The styrofoam "peanuts" were probably used to position the plant, or for drainage, or both. My experience with Angcm magdalenae is that it really needs good drainage - which that pot isn't going to provide. It likes to be a little drier in the winter but not bone dry. It's a relatively cool-grower, will put up with daytime heat if it can cool down at night. For your plant, once the bloom finishes (enjoy it and especially smell it at night, the fragrance is wonderful) I'd suggest moving it to a plastic basket. You can do that without disturbing the roots much, just slide it out of the pot, drop into basket and leave the medium in place. Fill in with bark, or loosely-packed sphagnum that will be very airy and tend to dry out.
In San Francisco, it should be quite happy growing outside, should love the humidity, your cool apartment should be fine too. (The Baker culture sheet in Orchidwiz indicates that in habitat it gets a temperature range from 91 deg F to 30 deg F . It is native to fairly high elevations. So you don't have to worry about winter very much if at all. (Again, just dryer in winter when it's cold) I agree with Keysguy, you should not give much more than 12 hours a day of light... it comes from an equatorial region where days and nights are pretty much equal. (It really doesn't need a lot of light even during the day... more like a Phal or Paph) And the fragrance develops in low evening light, you want to enjoy it!
