You're on the right path. My shooting completely changed when I started torquing all the screws and bolts to factory specs. I just have the Wheeler, and a cheap Tekton or something like that, it goes up to like 120 inch pounds. I'm certain there are better tools out there, but no more than I use them, they fit my need.
Have a Wiha adjustment up to 50in. Been great for years. I bought a kit somewhere and it had all sorts of different bits. Forget where I bought it. Hell to get old
