Hi Kei - Let's keep it simple. Indoors, the more sunlight a Jade receives the better it is. Outside it needs some protection - light shade is best.
Fertilizer is vastly over-rated - better to use less (half-strength) rather than more or skip it altogether.
Keep your Jade potbound and avoid repotting altogether. Allow the top third of the soil to dry before watering thoroughly until a bit of water trickles through the drain hole. Don't mist the leaves.
