Answer 1

You would need to place your union into a subquery:

SELECT  Hours,
        SUM(Hours) AS Hours,
        SUM(Hours2) AS Hours2
FROM    (   SELECT  Hours,
                    SUM(Hours) AS Hours,
                    0 AS Hours2
            FROM    Table
            WHERE   Name = 'xxx'
            AND     Description = 'Worked'
            GROUP BY Hours
            UNION ALL
            SELECT  Hours2,
                    0 AS Hours,
                    SUM(Hours2) AS Hours
            FROM    Table
            WHERE   Name = 'xxx'
            AND     Description2 = 'Worked'
            GROUP BY Hours2
        ) t
GROUP BY Hours;
