Answer 1

According to the Hibernate documentation, you can specify a where clause when mapping a collection:

6.2. Collection mappings

(…) The <map> element is
representative:

<map
    name="propertyName"                                         (1)
    table="table_name"                                          (2)
    schema="schema_name"                                        (3)
    lazy="true|extra|false"                                     (4)
    inverse="true|false"                                        (5)
    cascade="all|none|save-update|delete|all-delete-orphan|delet(6)e-orphan"
    sort="unsorted|natural|comparatorClass"                     (7)
    order-by="column_name asc|desc"                             (8)
    where="arbitrary sql where condition"                       (9)
    fetch="join|select|subselect"                               (10)
    batch-size="N"                                              (11)
    access="field|property|ClassName"                           (12)
    optimistic-lock="true|false"                                (13)
    mutable="true|false"                                        (14)
    node="element-name|."
    embed-xml="true|false" 
>

    <key .... />
    <map-key .... />
    <element .... />
</map>

(…)

(9) where (optional): specifies an
arbitrary SQL WHERE condition that is
used when retrieving or removing the
collection. This is useful if the
collection needs to contain only a
subset of the available data.

This is also supported at the <class> level.
