Answer 1

Just adding a bit to your original query:

SELECT * 
FROM Comment 
WHERE BlogEntryId = [?Blog Entry] 
AND (
    CommentId = (SELECT CommentId FROM Comment WHERE CommentDate = (SELECT min(CommentDate) from Comment))
    OR
    CommentCommentId = (SELECT CommentId FROM Comment WHERE CommentDate = (SELECT min(CommentDate) from Comment))
    )
