Answer 1

DefaultTreeCellRenderer renderer = (DefaultTreeCellRenderer) jTree.getCellRenderer();
    renderer.setLeafIcon(null);
    renderer.setClosedIcon(null);
    renderer.setOpenIcon(null);

The jtree uses CellRender, for example DefaultTreeCellRenderer, and you can dasable or change default nodes icon. Also, you can create custom cellRender and defined more dificult logic for you icon scheme.

tree.setCellRenderer(new DefaultTreeCellRenderer() {
                @Override
                public Component getTreeCellRendererComponent(JTree tree, Object value, boolean sel, boolean expanded, boolean leaf, int row, boolean hasFocus) {
                    JLabel component = (JLabel) super.getTreeCellRendererComponent(tree, value, sel, expanded, leaf, row, hasFocus);
                    ImageIcon iconPath = ((WizardNode) value).getIcon();
                    component.setIcon(iconPath);
                    return this;
                }
            });
