At the top of the board there are FAQS. In these you'll find tons of information about cloth diapering and also ratings on many different cloth diapers. There are also many resources on youtube so that you can "see" the cloth diapers. I would strongly suggest doing a cloth diaper trial. This way you can try out the different brands and types on your LO and see what works best. Different diapers fit different LOs differently. Good luck and feel free to ask any further questions you may have.
Re: CD-where to begin
You buy a few and try them out. There are ratings in the spreadsheet in my siggy. I've liked nearly everything I've tried; what I don't like I resell.
