Fig trees are weird - they have two crops of figs each year. Their first crop is actually formed in the fall and hangs on the tree all winter so having fruit before leaves is what they do.
The rocks in the bottom of the pot are to keep the plant from sitting in water. Not a problem if the tree is going into the ground. As the tree isn't getting much light, it will need less water. But you say it is very warm where you have it. If the leaves and branches are "stretching", better find a new home before its permanent home.
