From the steady flow analysis run editor, click on options and then select, "Set Calculation Tolerances...". For steady flow the default is 0.01 feet and yes you can change it.
As far as guidance, I'm not sure what to say. If you are modeling a deep river like the Mississippi you could make it lot bigger. If you are comparing RAS with a hydraulic flume study, you would want it really tiny.
