A couple things to add to your enclosure...
Be sure to add tons of foliage (brances, vines, fake plants, etc.) Keep them somewhat high so your cham feels safe. They need branches to explore on and hide out. You can search through the forums on peoples set ups to get an idea. Just besure the cage is complete before you put your little guy inside. They get stressed out when you move stuff around while they're in there. Your ficus tree is perfect, be sure to swap the soil out with organic soil, wash down the plant with regular dawn soap mixed with water in a spray bottle, and use medium sized river rocks to block the top of the soil. You don't want your cham digging or eating anything in the soil.
Make sure to have a perch specifically for the cham to bask. Usually this perch/branch can be alittle higher than other branches so your cham will be able to bask. Theres no basking light in your pictures so hopefully you picked one up. You can use a regular old 60w house hold light bulb and it will work the same as a $10 zoomed basking light lol. And the rule with basking lights is make sure it's atleast 8" away from the basking spot. Temps should never be higher than 85-90 degrees. Since your cham is pretty young, i'd keep the basking temp under 85-86 degrees.
You'd also want to develop some sort of drainage system. It will be a pain to clean up all the water drops everyday. Also it'll cause mold / bacteria if it's not taken care of properly. For my drainage system I just built a stand out of PVC and placed the stand inside a 28"x28" Washing machine water tray. It helps protect the table the cage sits on incase water leaks out the side of the cage.
Keeping a live plant is pretty difficult since it wont be getting any direct sunlight. For my light set up I have a T5 High Output double light fixture with a 6% uvb bulb and 6500k grow light. The grow light helps plants get what they need to grow indoors.
Hopefully i covered a few basics for a set up, there's allot more info but this should be good enough to get you started
And as other members mentioned, just be sure your cham is eating and drinking well.
