Yes, the best way to remove a DAG is to just condor_rm the DAGMan job 
itself.  DAGMan will then remove all of the corresponding node jobs.

Actually, this should not result in any POST scripts being run; in fact, 
any running POST scripts should be killed.  Years ago someone claimed 
that they ran into a case where many POST scripts ran when removing a DAG, 
but we were never able to duplicate the problem.  If you do condor_rm the 
DAG, and see POST scripts run at that point, we'd be very interested to 
see the dagman.out file...
