Or what is the best way? I had an Idea to create linked servers and that once linked I could find a stored proceedure somewhere that would run and get all the table names and data and create them on my MS SQL 2008 Server.  I only want a snapshot to be taken I do not need the data to be updated at all.

What Oracle version?

There is an Oracle package: dbms_metadata and a function called get_ddl in the newer versions of Oracle.

This will extract the structures.  I've not heard of a utility that will port the code automatically.

What about CTAS?  I don't know SQL Server that well so I'm not sure it will work, but I would think it should.

You should be able to do something like:

create table <tab> ... as select * from <tab>@<link>;

You could wrap that in a procedure that did a select on user_tables@<link> to loop through all the tables.

if you are using oracle 9i or later can you not just use oracle publishing and snapshot replication to achieve a copy

You will not be able to create an exact copy.  Something similar perhaps, but not exactly the same.

I think I need to be more specific... All I need is the tables populated with the data no code, no users and no permissions just tables with the same number of columns and the same number of rows that contain the same data.

If you have linked the databases then:  Then johnsone's post in http:#a35198971
or insert into table (select * from linked_table)

Do have DTS (Data Transformation Services) with sql server?

If they aren't linked you can create a delimited flat file.

SSMA is the way to go in this case
