AD5791 Reference configuration

I will be using the AD5791 DAC for precision waveform generation (~10kHz), but I need to be able to supply either a +/-5V range or +/- 10V range output.  My question is, in general would it be better to adjust the gain via the reference buffers or via the output buffer?  Or are there any tricks someone can provide to accomplish this in a better manner?  Also, I'm planning to use either the AD688 or AD588--are these suitable references for this DAC to take advantage of the precision?
