Keep you plant evenly moist and in a bright location.
Pinch back the growth often to keep the plant from becoming too leggy.

This plant is a fast grower and you should have a nice size plant in no time.

It likes moist, but well-drained soil. I would let the top of the soil dry out between waterings. I suspect too much moisture. I also would hold back on the misting.
It likes a sunny disposition, if you can offer it more light.
Go ahead and trim it back a few inches to encourage growth.
It probably is suffering from shock from the change in environment. It should perk up soon.

I did an exhaustive online search and cannot find how to tell the male and female plants apart. When they flower, you can examine the reproductive organs to tell. The article below tells which has what. If one fruits, you will know you have a female. Most articles just say to propagate by softwood or semi-softwood cuttings.

Generally, you will obtain many plants and wait to see flowers. Once you do, you may need a magnifying glass. A female plant will have, only, one reproductive stigma. It will be in the center of the flower. The male flower will have several stamen, which will be covered in pollen.
