Some sites (incl. the one I'm at) use Quattor (http://www.quattor.org/)

Not really, although there's some overlap.

Resource managers like Torque (PBS) are in charge of ... managing the 

Job schedulers (e.g. Maui, MOAB) decide which job gets to start next, 
and talk to the resource manager (i.e. poll for available resources, 
instruct which job should start next, etc.).

See the "Small HPC Centers" survey I pointed to above.
