Yeah, I'm pretty sure boiling them will kill them and then they won't sprout, but they could be served as cooked beans.
For sprouting I soak overnight, then drain and allow to sprout. I use a little GSE (with preservatives) in the soak water, but it's not strictly necessary. You can also use a tiny bit of bleach, which is what is done commercially, but then you have to worry about very thorough rinsing.
Don't try to sprout red kidney beans (and presumably any close relatives) but pretty much everything else that's commonly available is safe to sprout.
