what do you mean with appropriately? If that is the geometry that you  
want to get as your final state.. that's fine.. but don't expect
the topology generator to work properly with it..

a typical hydrogen bond (O1-O2) for bulk water is ~ 2.8 angstrom..   
(as you said yours is 2.0 Angstgrom)..

Sorry.. I don't understand why/where you are expecting an help  
changing the geometry of the final state of the NEB.
Perhaps, I was not clear in my last message:

You've setup a bond-breaking reaction with a classical FF:
1) You didn't provide any parameter file for the classical FF (!)  
(and this causes the abnormal termination of cp2k)
2) You cannot do BB* with CP2K, using a classical Hamiltonian.
