As the track is being laid is there still a need for isolated joints and again are there more or less of these??
You don't need to isolate anything unless you have too many trains for the power output of the controller.
In fact you really want to avoid isolating sidings when the point isn't set to go there so you may want to add extra connections to the sidings if the points do power routing.
You probably want to make a programming track to connect to the programming output on the controller, a few straights and a power connector is all you need and it doesn't need to be a part of the layout.
