Taking cuttings from a Kalanchoe

Hi Everybody

I bought a couple of Kalanhoe pot plants at the beginning of the year just to put on my hall window ledge, the small flowers stuck around for months and slowly died off about 6weeks ago. I don't think they're supposed to last forever anyway?
Will the plants develop new flower blossoms or do i need to do something to encourage them ?
I've noticed both plants have grown a number of new stems and lots of new shinney leaves, whilst a number of the original large base leaves have curled up a little and turned yellow (most of which i've trimmed off).
Also i've noticed the new stems seem to have what look like roots developing where they branch off the main stem ....can these stems be cut off and rooted separately in new soil ?

Thanks in advance
John
