You will have to wait until he/she is mature to figure out the sex. I had one of my greys for 3 years before figuring out that she was actually a he. He never called, was a pretty good size, so I assumed female...one day I found "her" in amplexus with my big female.
UV light is not necessary. There is no research that suggests they benefit from it. My greys typically like to claim the highest perch, I don't know if it's necessarily for the light or because it's the highest perch. In the wild, they like the lights because lights=bugs at night. Easy pickings.
Right now you want to have him in quarantine conditions. Keep him in a tank with damp, unprinted, paper towel on the bottom that you change every 1-2 days. A water bowl that gets cleaned daily and is refreshed with dechlorinated water (most here use seachem prime to dechlorinate.)
It would be helpful to start teaching your frog to bowl feed now. Greys can get fairly aggressive while eating and take in a mouthful of substrate, which isn't good. When you get your crickets, place them in a glass bowl. This is helpful as you can see exactly how much your frog is eating to better assess his health.
You could also add a branch or two in there if you wanted to help keep him happy, but you want to make it all very easy to clean and observe. I would recommend to get a fecal test done considering he is wild caught. That will prevent you from having issues down the road from parasites and etc.
