Congratulations on your win... gosh I wish my society has Paphs and Phrags as prizes for their raffles!
Now, Paph spicerianum is a fairly easy orchid to grow. Early morning light is good so an east facing window would be good for that. Just make sure the plant doesn't get too much of the day's hotter sunlight. As usual the moist but not wet applies and some air movement would be good, so open the window every so often when it isn't chilly outside. Temperature wise, this is a fairly forgiving plant and mine has withstood temps from 5 celsius to 45 celsius!
Phrag bessae can withstand a bit more light than the spicer but again hot midday sun is a no no. Oh, and also, put the pot sitting in water. This species of Phragmipedium likes wet feet.
So, good luck with the two new 'chids and looking forward to seeing them bloom!
