Insulation above pony wall

I can't seem to find an exact answer on this, although it's touched upon in a few different threads. I have a walkout basement that I am in the early stages of gutting and refinishing. First goal is to insulate it better, since it's quite cold in the winter (I'm in southern NH). About a quarter of my poured basement wall is a pony wall. Above it is older wood paneling with fiberglass insulation that is quite gross. I had a bad mouse problem the past few years and I can see where they have all nested.... Anyway, what's the best solution for insulating above the pony wall, other than spray foam? I just can't afford that. I didn't know if I could use rock wool, or put some xps against the plywood first... Just not sure :)
