Answer 1

Since this is sql server 2008 you can't use EOMonth (that was introduced in 2012 version).
You have to do some date adds and date diffs:

SELECT DATEDIFF(DAY, 
                GETDATE(),
                DATEADD(MONTH, 
                        1, 
                        DATEADD(DAY, 1 - DAY(GETDATE()), GETDATE()) 
                       ) 
               ) - 1 

explanations:
DATEADD(DAY, 1 - DAY(GETDATE()), GETDATE()) gets the first day of the current month, the wrapping DATEADD adds one month, and the wrapping DATEDIFF returns the number of days between the current date and the first date of the next month. This is why you need to subtruct 1 to get the correct number of days.
