Hi L.,
I think it is great that more Mom's are 'going-green'. It is so important to the health of our children (and us, and four-legged furry family). Here is my advice...
Diapers:
I never tried cloth so you will have to ask someone else about these.
G-Diapers
I used these until they outgrew the first size.
LIKES: Breaks down in compost in 1 month. No icky gels (what is that stuff). lots of cute styles.
Dis-likes:LOTS of laundry (with a drought-not so cool). Not so great for 'out and about trips'. The velcro would come undone and my 1yr olds (adopted and brought home at one) would wake up with the diaper stuck to a blanket and a big mess in the bed. It also seemed to be rubbing them and creating firction (ouch). I have heard that they have updated and inhanced their diaper so it may be better.
7th Generation
These are good. Not cheap They are unbleached, with no icky stuff added to them. They take more time to break down in our landfill.
Whole Foods Market Brand
If you can get a GOOD fit I like these for all the reasons of 7th gen, plus about $3-$4 cheaper. They don't have leaking problems. They are they stongest I have used.
BodyCare...
My favorite is Claifornia Baby, it is pricey, BUT a little goes a long way and bodycare gets absorbed into their bodies through the skin. Burts Bees is good option as well. I was not impressed with Welda (sp) and they are really over-priced.
Household...
My favorite splurge!! Meyers, you can buy this anywhere now. but it is a splurge!
Whole Foods Market brands and the Target brand Method are also good choices.
A little baking soda works well as a cleanser and that is all natural and very cheap.
Also..if you are going green...skip any chems on your outside grass. If you use bottles or sippy cups born free is free of all the nasty bad plastics but $$. For a cheaper option Munchkin brand does not use those nasty plastics in their products. Hope this helps!
