Answer 1

That's little tricky.. Let's assume you have following binding for your SPTreeview

<DataBindings>
                <asp:TreeNodeBinding SelectAction="Select" NavigateUrlField="" TextField="EncodedName"
                    Target="_blank" ValueField="Name" />
            </DataBindings>

Then, in PreRender, you need to set the SelectedNodePath as shown below

 protected override void OnPreRender(EventArgs e)
        {

                WebTreeView.SelectedNodePath = "value that corresponds to current web";

        }

Answer 2

using TreeView instead of SPTreeView:

protected void LeftNavTreeView_OnPreRender(object sender, EventArgs e)
                {
                        LeftNavTreeView.CollapseAll();

                        var treeNodeToExpand = LeftNavTreeView.SelectedNode;

                        while (treeNodeToExpand != null)
                        {
                                treeNodeToExpand.Expand();
                                treeNodeToExpand = treeNodeToExpand.Parent;
                        }
                }
