The sand is pretty easy to take care of IMO. Instead of pushing the vac into the gravel just hold it a little above the sand to suck up the poo and anything else laying ontop of the sand. And I kinda stir my sand up every so often make sure nothing sits buried to long. If you are goin to move your established filter or filters that will give u a jump start on your cycle. I have never transfered directly from one tank to another if that's what your planningn on doing so I'm sure somone else with more experence wil give you more detailed help on that.
