Just to clarify the point, you still have to choose a Collation -Page Code - for your non-Unicode data.
The Collation you choose does not affects data stored in Unicode datatypes e.g.: nchar, nvarchar and ntext.
Last but not least, at installation time you have to set two different Sort Orders, one for Unicode and one for non-Unicode data.
