A good resource for support is the state school for the deaf or one of those formal programs specificly for dhh kids.Find support. Some areas have playgroups/support groups for families of newly identified children. If you are religious, find a local church with signed/interpreted services. They're a great place to make contacts.
Just a word of advice. I know it's difficult to figure out which methodology to use. I would use a child centered approach and offer him a variety of approaches. Meaning get him speech therapy but also teach him Sign too.Do not let yourself be pushed to make any decision for your child. Everyone has their own opinion, but he's your son. Your opinion trumps all.
Oh, and you may be under the impression that Deaf people are against CIs. CIs for kids who require them right off the bat are being a lot more accepted then in the past. Heck, many Deaf folks here have gotten implanted. In five or ten years, they'll be accepted across the board!
