This appeared on the list sometime back (probably has reached FAQ status). 
It worked for me WRT the shrinking an open partition problem.  YMMV.

Heh... spent two nights on this one setting up my machine.  The
solution is easier than it seems.

1) 'disklabel -e -r /dev/rrz2c' & add a partition 'a' (doesn't matter
   how big).  Save it.

2) 'disklabel -e -r /dev/rrz2a' <-- this is the critical line.  Notice
that the "open" partition is now _a_.  Modify your c partition to your
hearts content.  Save it.

3) 'disklabel -e -r /dev/rrz2c' <-- add your other partitions.
