My calla lillies unexpectedly sprouted and bloomed while wintering them in the basement. We are zone 4 and now I'd like to take them outside, but am not sure how to plant them because of the foliage and flowers.

Go ahead and plant them out as usual. The will be fine, just a little eager for warm weather, like the rest of use cold climate gardeners.
Shelter them just a bit, just like you are hardening off a new plant from the garden center--to help them adjust to the sun.
