Yes, you still need to do the I-864. You don't really need to do an AOS from the sounds of it, he can just file an I-130. Takes about 7-9 months to get approval but you're allowed to visit while the petition is pending. Plus it's cheaper.
I can't really recommend you do the AOS as a visitor, it's a dicey thing to do, because technically you are lying about your reason for entering and if USCIS think you are that can cause problems. That's not to say people don't do it which is why immigration consultants mention it.
