For when your baby is new, I would suggest mostly prefolds & covers. You will be changing a lot of diapers at first, and prefolds are easy to use (you don't need pins or snappis), quick to wash & dry, and inexpensive. Also, get a few diapers just to try out so that you can see what you like & what fits well on your baby. Personally I like fitteds with covers.
For wipes, I use baby wash cloths. I actually prefer the cheap, thin kind - you'll need at least 30 - and then I just use plain, warm water with them.
