I have the same size screen cage, i just put a nice shefflera in it, i have a hanging pothos pant, and a ficus tree, right now my cham is prolly overwhelmed by the vegatation now. When i get a camera i will get a pic. But in my cage about12 inches from the top a have a large bendable vine/branch in a spiral type shape going from high to low. i have some sanblasted grapevine in one corner i used zip tiesto secure it to the frame and the screen, be sure to make the holes just big enuff to get the zip ties thru it, crix can find them
. I have a jumbo grapevine one the bottom of the cage, and about 6 benda vines running all over the place, now to the plants, The scheff i have on an iron 3 legged stand it holds upto a 12 inch pot, the nice thing about it is the legs enable it to have stuff going under it, the top of the scheff is about 6 inches from the top of the cage,The hanging pothos (4.99@walmart) i put a hook above the cage,be sure it will hold a plant!!!,iran the chain down to the top of the cage to where one half link is stickin thru cage(cut small slit in cage)..i chucked the ugly plastic hanger in favor of a nice woven one.(be sure u can adjust the hieght of it)set it to where the plant was about half way down the cage.the pothos i snice cus u can run branches of it too various other climbing things, and i have the ficus on the very bottom, wow pretty long post, but hope that gives you some ideas. will get pics up soon
