You got some good responses - yes, you need to prep the organic inserts, I would boil for 10-20 minutes (no detergent) and then wash in hot with a little bit of a free and clear detergent in the washer, followed by a cold rinse. I tend to air dry all of my covers (Flips, BG 4.0s and a variety of others), but usually put the inserts in the dryer because it makes them softer and easier to stuff, or just softer when touching the bum.
I agree that if your baby is teeny, you might not get a great fit, so if you think that your baby will be really small, you can look into a newborn stash. If you're not grossed out at the idea of a gently used stash, most people sell theirs when their babies outgrow them. The upside is that you can get some almost new diapers for really cheap since the babies only wear them for a very short time. You can check out Spots Corner on Hyena Cart for some used newborn diapers. If you want to get some newborn diapers new, I highly recommend Doodle Dypes - Sandy, the owner, makes an amazing one-sized all in one for 12 lbs and up, but she also makes a one-size newborn diaper she calls the Dynky. She has a shop on Hyena Cart (http://hyenacart.com/doodledypes/), and has an active FB page (http://www.facebook.com/pages/Doodle-Dypes/264758218226), where you might be able to snag a stash of used ones from one of the mamas.
We have lots of different types of CDs in our stash, I started out with BG 3.0s, and then started using some fitteds and other pockets. You might have to try a sample pack once your baby arrives (and gets to the 10 lb. mark) to see which diapers fit him/her best. Your favorite diaper will likely depend on how slim/chunky your baby is (if you have a chunky baby and want to know what we use, message me!), and how heavy of a wetter they are. You might find that you prefer different diapers for different things. In any event, the cloth diapering community is an awesome one, and there are lots of good resources.

http://www.theclothdiaperwhisperer.com/ (tied to Kelly's Closet diaper shop, she offers a free diaper with a purchase pretty often, but I hate paying shipping, and it took a long time for my packages to reach me...I get impatient with fluffy mail. But you can't beat a free diaper!)
Congratulations on your new baby, and have fun cloth diapering!! Message me if you have any questions later!
