Answer 1

Try:

SELECT x.column1,
       STUFF(SELECT ' - ' + t.column2
               FROM TEST t
              WHERE t.column1 = x.column1
           ORDER BY t.column1
            FOR XML PATH(''), 1, 1, '')
  FROM TEST x

Reference: STUFF

Answer 2

You can use the Coalesce function to sort you numbers in a list. Hopefully this gives you a start:

Declare @T as Table (Col1 varchar(35), Col2 int)

Insert into @T(Col1, Col2)
Select 'Test', 1

Insert into @T(Col1, Col2)
Select 'Test', 2

Insert into @T(Col1, Col2)
Select 'Test', 3


DECLARE @X varchar(200)

SELECT @X = COALESCE(@X + ' - ', '') + Cast(Col2 as varchar(5))
From @T

Select @X
