Answer to question 1: A quick way to get DataGridCell from DataGridCellInfo:

    public DataGridCell GetDataGridCell(DataGridCellInfo cellInfo)
    {
        var cellContent = cellInfo.Column.GetCellContent(cellInfo.Item);
        if (cellContent != null)
            return (DataGridCell) cellContent.Parent;

        return null;
    }
