Answer 1

Add a Context Menu Strip to the form with a 'Rename' entry and set that to be the ContextMenuStrip of the TreeView

this.treeView1.ContextMenuStrip = this.contextMenuStrip1;

Then on the 'Rename' click event do your renaming, checking first that there is a TreeNode selected

private void renameToolStripMenuItem_Click(object sender, EventArgs e)
{
      if (treeView1.SelectedNode != null)
      {
          // Do renaming
          TreeNode node = treeView1.SelectedNode;
          node.Text = "New Text";
      }
}

Answer 2

The TreeNode.BeginEdit method allows you to put a node in edit mode (given that LabelEdit = true for the TreeView control).
