1- Ok
2- I'm not convinced that it is always necessary to use a realistic stiffness if you are interested in large strain, dilatancy, internal friction,... 
3- For large Dmax/Dmin, it could help to use density scaling (see examples/timeStepperUsage.py). I don't think floating particles are the source of problems, they are not highly dynamic usually and they carry small force (hence small unbalanced force).
