How is it possible to find and remove items?

flyGrid1->Rows->Items->Add(newNode); and newNode->Items->Add(newNode2); return an integer of its position rather than a pointer to it, so how can you find it again?

You can find node by it index -
[c#]
int index = node.Index;
if (index != -1)
{
  NodeBase parentNode = node.Parent;
  parentNode.Items.RemoveAt(index);
}
but more convenient way:
[c#]
if (node.Parent != null)
{
  node.Parent.Items.Remove(node);
}

Since it is an index, won't it change if the data is sorted or if an item is inserted?

This index is dynamic (can be changed after sorting, removal or insertion another nodes), when you require Node.Index you receive current index in the parent nodes collection -
it is the same as following code
[c#]
public int GetNodeIndex(NodeBase node)
{
  NodeBase parentNode = node.Parent;
  return parentNode != null ? parentNode.Items.IndexOf(node) : -1;
}
