I would cut the blooms off and leave the stem. Cut any buds off on the others. If you have a shady place I would plant them there just for the rest of this season. The stems and leaves need to green up to feed the bulbs but I suspect high heat would not be good for them. Oh, and please report back to us later on how it works out for you. Getting some actual information will help others who may ask the same questions!
Glad to hear you got the PNWLS information. Have you gone to their site and looked at the photos of last springs offerings? It will give you an idea of the choices and pricing you can expect.
