Actually I _never_ used XML to configure the cluster; instead I did everything (create, rename, edit, remove) using "(SLES) crm shell. Still you can "crm configure load xml ..." if you ever need to load XML. And nothing is freezing for ages if I update the configuration: Once committed, changes take effec timmediately. Finally be aware that the cluster still has to find out the difference between old and new CIB to create the actions needed, so I really don't see a reason to replace the CIB unless completely resetting the cluster (and then there should be no problem stopping resources before).
