He's looking great.
As JR trains JS more than JS trains JR, my suggestion is to rotate between passing, one on one (forwards) and JR for a season.
One on One forwards will train IS, JS, DR and HA.
Outside Shooting will help with JS as well as, obviously, Jump Range.
Passing will also raise a few skills as well.
I think if his inside shot is around 9-10, it'll be enough for a SG to be effective inside..
Regarding ID, I feel that you may want to raise it a few if you find the time to train it, it helps in a Man to Man defence when the opponent drives to the hoop, but otherwise if you play zone defence most of the time, it shouldn't be a worry.
