In my opinion nothing beats vendor's documentation, try this http://msdn.microsoft.com/en-us/library/dd894051(v=SQL.100).aspx

I think compression may be an enterprise only/Developer version only feature.

If you don't have neterprise edition, you won't be able to use it, i think.

there's a really good MS article on the advantages, what to expect, etc:

http://msdn.microsoft.com/en-us/library/dd894051(v=sql.100).aspx

as for the specific how to compress:

the basic DDL is like this:

CREATE TABLE <table_name>

(<column_names>)

WITH (DATA_COMPRESSION = ROW | PAGE)

ALTER TABLE <table_name>

REBUILD PARTITION = 1

WITH (DATA_COMPRESSION = ROW | PAGE)
