It sounds like you have a really good handle on what he needs. Hopefully his mom follows through, esp since her new hubby doesn't want to continue with the fighting. It would be good to check for any laws about grandparent's rights. Some states have laws for this, some don't. Here is a site that describes the laws in Tennessee, but it is in legalese.

Getting slapped with a court fight over grandparent's rights is NOT going to be fun, so make sure you are prepared.
For a neuropsychologist you should try a teaching hospital or a children's hospital. It may take some calling around. Try a google search first, would by my suggestion.
Risperdal can work very well. It seems like he is on a low dose, and that it is working! That is wonderful. It made quite a difference in my son. Not as dramatic as when we first tried adderall, but still noticeable. Risperdal is also used on an "as needed" (aka prn) basis. You might ask the psychiatrist if you can give it that way if he ever has a big meltdown. Not on a daily basis, but for those times when he is throwing chairs or hitting, the really out of control times. I think they even make risperdal in those fast acting melt in your mouth versions. Those are easier than trying to get a violent child to take medications.
It is wonderful that he is motivated and eager to earn points to get a new toy. Just be careful that the rewards don't get too big or expensive. Also be careful that he isn't getting points for everything. There need to be things a child does just because he is part of the family, NOT because they get rewarded. Many here have run into those problems with our difficult children. At one point my son demanded points for eating a meal. He even tried to get us to agree to give him points for breathing!! ROFL we said no, go ahead and stop. He couldn't stop argueing at us (not with us because we went on with our usual activities) long enough to hold his breath for 15 seconds!!!
It seems he is settling in with you, feeling more comfortable, and that is a great thing to see.
