Here is a script for generating INSERT statements for 1 table. You could modify it for all tables or a subset. I use it when generating a subset of data for testing. I think someone here on this forum provided it .... Sorry, I did not note who it was (although I usually do try to keep the authors name).

Edit: Maybe I got it from here:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=53420

-- Instrucions!
-- Change current db
-- Change source table (in red)
-- Change sample rows (in red)
-- run to generate insert statements
-- optional 'WHERE' clause near the bottom to specify records
use MyDatabase

DECLARE @tableName varchar(100),
@seedCnt int

SET @tableName = 'MyTable' -- Table Name
SET @seedCnt = 50 -- # of records to select

DECLARE @execStr0 varchar(8000),
@execStr1 varchar(8000),
@execStr2 varchar(8000),
@execStr3 varchar(8000),
@execStr4 varchar(8000),
@execStr5 varchar(8000),
@execStr6 varchar(8000),
@execStr7 varchar(8000),
@execStr8 varchar(8000),
@execStr9 varchar(8000)
