I'll look into requesting resources, as well specifying resource quotas. I very 
well may end up using a forced complex on each queue (except our 
shortest-running one, which was our past model) to strongly encourage users to 
specify a queue. As far as drmaa, we had our shortest (one hour) queue defined 
as the default in sge_request. It worked fine for batch scripts, but in drmaa 
when we defined which queue we wanted to go to (1-day, 4-days, etc.), drmaa 
jobs would always go to the 1-hour queue:

else {
      errnum = drmaa_set_attribute (jt, DRMAA_REMOTE_COMMAND, 
"/home/user1/scripts/c/sleeper.sh",
                                    error, DRMAA_ERROR_STRING_BUFFER);
 
      errnum = drmaa_set_attribute (jt, DRMAA_NATIVE_SPECIFICATION, "-q 4-days",
                                    error, DRMAA_ERROR_STRING_BUFFER -1);

It didn't matter whether we used drmaa with java or c, it would always go to 
the 1-hour queue. I haven't figured out why it is/was happening yet, but by 
setting up a test environment and leaving the global sge_request without a 
defined queue, drmaa jobs ran in whichever queue I specified using the above 
listed parameters. We've since done that in our production environment and 
everything is working as expected.

Don't submit to a queue but request resources. The rest will work automatically.

In case you really want to address a queue you could also attach a complex to a 
queue which must be requested as you suggest, this could even be set to forced 
in case no other jobs should slip in.

Or use an RQS, so that certain users have zero slots in other queues.

What problem did you face in combination with drmaa?
