I’m not sure of your objective….however….If my tree I would bury those roots shown in the last photo. Could be some Sun drying (not sure where you live though). Some leaves likely dried and deteriorated due to potting at a time when the leaves were full out.
I’d also suggest a moisture stick placed out further the pot which is probably where the smallest feeder roots are located. It will tell you the moisture further away from the rootball.
Another question. When you replanted the tree did you poke around the substrate with a chopstick (or similar tool) to make sure the soil area is settled in well throughout the root zone?
You can clip off dried leaves whenever you want. Those dry leaves are not going to re-green themselves. If dried, they’re done. Leave a small stem so you don’t injure the bud nearest the branch.
