How Deep Should My Sandbed be?

2" should be fine there really isnt a set depth just what you like. I would get new sand if i moved my tank to avoid getting nasty stuff in the new tank.

I don't throw away old sand. It gets rinsed and dried out for the next tank (or tank move).
 
If your not going DSB (i.e. 6") then I would keep it under 1". That will just make it easier to keep clean in the long run and have less chance of building up detritus in the sand.
