Mickey, check your rules, I'm not clear that all of that is STL legal (e.g., fenders, headlight; make sure you're not reading STU, the prep rules are different).

But that said, you're on the right track. Do you have IT-mandatory power steering? That can go. Plastic panels, plastic "glass", etc. Don't expect a fuel cell to be lighter; in fact, I suggest it and its ancillaries it would be heavier than a stamped-steel factory tank.
