Instead of SSIS, google this:

sp_help_revlogin

The output from that will produce output to create the users.

This code will generate code to create the users and add them to the proper server roles:

SELECT 'EXEC sp_addsrvrolemember @rolename = ' + QUOTENAME(usr1.name, '') + ', @loginame = ' + QUOTENAME(usr2.name, '')

FROM sys.server_principals usr1

INNER JOIN sys.server_role_members rm ON usr1.principal_id = rm.role_principal_id

INNER JOIN sys.server_principals usr2 ON rm.member_principal_id = usr2.principal_id

As for the permissions inside each database, go to Books Online and look up sp_helprolemember. That can help you create a set of scripts to get you started.
