This is my old, and long since sold, '86 FZ750. The photo is up above Cal State Hayward, where I lived once upon a time.
It sounds like you've got it covered. You can get aluminum hex socketed screws to replace almost all of the phillips headed screws, making things much easier to remove in the future, even gold anodized ones to match the engine trim. Also, use anti-seize compound (I recommend PermaTex brand) on all of the threads going into both steel and aluminum. To successfully get the stuck phillips heads out, I've alway used a manual impact driver. That usually prevents stripping out the cross.
