do I need to be repotting the babies

So I bought this Ananas plant and it had a bulbous flower on top.  the flower then wilted and died, you can see the brown stem still poking out.  The plant has never reflowered however it seems to live on and seems to now to have had babies which you  can slightly see under the leaves.  I am unsure what to do now with the plant. The leaves all seem good and strong, should I repot somehow the bables underth leaves?  Also how can I get it to flower again.  Any help gratefully recieved.
