signing with a young child is great! here are some places to get started.... http://www.weehands.com/dictionary.htm
and http://www.signingtime.com/ look under fun stuff for free things to do with your baby. she does have a pbs show also that is fun for kids of many ages (my 5 and yr old watch it with the baby). I think that the best way to teach a baby to sign is to use ASL. it is a full language that can be used the rest of their lives. just teach them the real signs for everything. they will modify it and make it work for them. as time goes by they will start to do all of the signs correctly. I started to use sign with my roommates baby at 7 or 8 months old. now at 18 mo. she say about 5 words and signs about 25 or 30. she gets so excited when she learns a new sign.
