qstat -Bf gives useful output.  I usually compare the  
resources_available.* and resources_assigned.* values (by hand, but  
this could be automated).

For example:

# qstat -Bf | grep '[available|assigned]\.mem'
     resources_available.mem = 56gb
     resources_assigned.mem = 7549747200b

(..I've never looked into whether I can force those to be reported in  
the same units..)

# qstat -Bf | grep '[available|assigned]\.ncpus'
     resources_available.ncpus = 28
     resources_assigned.ncpus = 26

That could be a starting point for someone looking for an easy way to  
get the information.
