I wouldent recommend housing males and females together. I also wouldent recommend housing males together because they'll fight and one might end up dying. You can however house females together with the number dependent on how big the vivarium is. Usual rule of thumb is 2ft of vivarium floorspace per gecko with an additional square foot of floor space for each additional leo. Although, i personally advocate as much room above this rule as possible so that they can roam around and go on gecko patrol.
As for heat rocks, if your gonna use one use a thermostat, this is a must! BUT, if it fails, why risk cooking your pet..just a thought.
