Who suggested that to you? Just wondering because I work in recruitment and you really don't need to send anything else along with your CV, apart from a covering letter. The covering letter should target the job specifically and say why you'd be a great fit for it.
But you don't need to provide written references - employers will want to obtain verbal ones themselves. You may need to provide copies of various certifications at some point in the application process, but you will be asked for them later on if so, you don't need to send them with your CV initially. That said, you should of course read the job ad to see if they ask for anything further and if so you should provide it, but it's pretty unusual.
In fact I don't even have a copy of my degree to put with an application, it was only issued in a very large format and was framed so I can't really photocopy it!
