Good morning Steve The more critical of your repairs is the wing separation so that is the one I am going address. You cannot but glue back together and just fiberglas any thickness that is an inflight failure just waiting to happen. Now the problem is that it is very difficult to attempt to remove an original spar that is inlaid between a top and bottom spar as well webs either front or rear or both for a box section.

The best solution to at least have the original strength or better is surgery, removing sheeting (far easier if top and bottom) and cutting a spar doubler. You can use just a single front or rear as well as both for ultimate strength and of course if you choose both you can use a thinner doubler.

This doubler should go out as far as the original and be the full depth of the wing no less. Use only birch aircraft plywood. The affected first and second bay ribs will need to be cut back a quarter inch or so and after the doubler(s) are epoxied in the small gap is filled in with sheet of the same thicknerss Finally the resheeting is done.
