Drawing a collapsible indented tree with d3

With these it helps I'll update my answer as I work through your questions.
the root/start node is redrawn while expending a tree branch, resulting in overlapping the left and down arrow, see SCL line.
code :
node.select("path").attr("transform", function(d) {
    if (d.children) {
      return "translate(-14, 0) rotate(90)";
    } else {
      return "translate(-14, 0) rotate(0)";
    }
});

Hope that helps You have to add a function for that in your json loading. Check that example : http://mbostock.github.io/d3/talk/20111018/tree.html

To fix this issue Just because the sample code "forgets" the selected node, doesn't mean you can't add it yourself:
code :
// Toggle children on click.
var lastClickD = null;
function click(d) {
  if (d.children) {
    d._children = d.children;
    d.children = null;
  } else {
    d.children = d._children;
    d._children = null;
  }
  if (lastClickD){
    lastClickD._isSelected = false;
  }
  d._isSelected = true;
  lastClickD = d;
  update(d);
}

// on the selected one change color to red
function color(d) {
  if (d._isSelected) return 'red';
  return d._children ? "#3182bd" : d.children ? "#c6dbef" : "#fd8d3c";
}
// we used to set the text on enter
nodeEnter.append("text")
  .attr("dy", 3.5)
  .attr("dx", 5.5); 

// but now we change it on update based on children
node.select('text') 
  .text(function(d) { 
    if (d.children) {
      return '+' + d.name;
    } else if (d._children) {
      return '-' + d.name;
    } else {
      return d.name;
    }
  });

around this issue Since you didn't share your code, but just Bostock's one, this answer will be tailored to that bl.ocks.
What you want can be done changing the nodes at the first level, with:
code :
root.children.forEach(function(d){
    d._children = d.children;
    d.children = null;
});
