That looks much less bad than my first balsa build I ever did for sure.
I believe the Skylark kit, like the eaglet, has little supports that fit in the holes in the fuselage sides. They go next to the supports for the fuselage stringers that are placed about at the midpoint of each hole. Here's a really early photo of my eaglet with one of the pieces installed in the rear hole:
I'm pretty sure they don't really do much of anything structurally, they're just there to help the covering look nicer.
Unfortunately I didn't take any pictures of my gear being assembled. Basically you will have two split half ribs that hold the gear wire in place against the main rib and it's sandwiched with a complete outer half rib. The .500" bend at the top of the gear will rest against the leading edge. I'd suggest soaking all of the balsa pieces with thin CA after assembly just to harden them a bit. I hope it makes some sense. I'll include an assembled picture of mine but likely won't show you much.
