Answer 1

Add this to the RadioButtonList OnSelectedIndexChanged .

    protected void rdlist_CheckedChanged(object sender, EventArgs e)
    {
        //uncheck all checkboxes
        rdbtn1.Checked = false;
        rdbtn2.Checked = false;
        rdbtn3.Checked = false;
        rdbtn4.Checked = false;
        rdbtn5.Checked = false;
    }

Add this event to all other RadioButtons

    protected void globalRadio_SelectedIndexChanged(object sender, EventArgs e)
    {
        //uncheck all checkboxes
        rdbtn1.Checked = false;
        rdbtn2.Checked = false;
        rdbtn3.Checked = false;
        rdbtn4.Checked = false;
        rdbtn5.Checked = false;

        //uncheck all checkboxes in the list
        foreach (ListItem listItem in rdlist.Items)
        {
            listItem.Selected = false;
        }

        //re-check the clicked radiobutton
        RadioButton rb = sender as RadioButton;
        rb.Checked = true;
    }
