I don't tell anyone to hold their spots. I just bounce the ball, blow the whistle, and point in each direction to indicate where each team is going. If I see non-jumpers encroaching onto the circle, I remind them to stay off the circle. Otherwise, I just toss the ball after a random interval of time, and off we go.

If the rules say the jumper can't be substituted for except for a few enumerated exceptions, and none of those exceptions happen, he can't be substituted for, period. If a free thrower can't be replaced, and jumpers and free throwers are treated equivalently by the rules, at least when it comes to substitution, it then stands to reason that the jumper can't be changed unless there is a new jump ball situation, something prevents him from participating (injury, illness, or disqualifications), or the jump ball situation ends some other way (e.g. technical foul).
