You're learning a LOT from all this.

The only real hint I can offer is that you really did not need the tri stock. If you had done the rib noses with the grain going the right way first off you could easily have given them enough stiffness to resist the usual handling loads with a simple flat sheet stock gusset triangle off one side per rib to the spar and no gussets at the leading edge. Even then the gussets would be there solely for some toughness for handling until the leading edge sheeting was applied. At that point the sheeting will take all the loads nicely.

But this is a relatively small point to ponder for next time.

Once you're all done be sure to balance the wing out by putting a small weight on the heavy side. Your repairs will have added some weight to the badly busted up side compared to the relatively lightly damaged side. Although considering it's an ARF if you used a lighter wood for the sheeting on the badly damaged side for the repairs it might come out the same weight as the original wing. Balsa has such a wide variation in density from soft and light to hard and heavy that this can easily happen.
