If you're talking about the black metal inside window frame then yes, it must be installed in order to keep the window from falling out. If this is not what you're talking about, then pictures may help determine what it is.
EDIT: After rereading your post it dawned on my that you may be talking about the thin metal plates behind the luan. If this is the case then you may not need to replace it. They're used to give something to screw into when attaching things to the wall. If nothing is being attached then you don't need it. Typically things like floor cabinets and curtain gathers are screwed or riveted to the metal plates through the inside luan.
If you don't have any delamination or water behind the blue insulation (very unlikely since you do have damage), then you can just repair the inside luan. If there is ANY moisture behind the insulation then you need to remove the insulation and the outside luan behind it and replace that luan as well. More then likely the outside luan is in worse shape then the inside. On my 92 LY I had to strip the wall all the way to the outside fiberglass for most of the road side and a little on the curb side. You'd be amaized at how much water will be soaked into the luan behind the insulation. Once dried out, you can reuse the blue foam insulation.
I did use Gorilla Glue on mine and it worked quite well. I used a plywood panel on the outside that was held in place with 2x4 props and then used bowed poles on the inside to provide the clamping action. I reused the blue insulation once it dried out. I cut the luan to match the shape of the insulation and then glued that to the back of the insulation. I then glued that to the outside fiberglass with the luan facing the fiberglass. I then used luan in the largest sections I could cut to cover the inside. Again using the Gorilla Glue to bond everything. Take the windows out and it makes the job much easier and gives you much better results. You can use clamps and boards around the window frame to really get some good clamping action. The stronger the clamp the stronger the Gorilla Glue bond will be.
