you're in luck mang!!
(except for the scraped paint on minerva's top of the windshield
)
to fix the roof and above the headlights,backsand it,then plastic polish it.
backsand=
1st grit= 240
2nd grit= 320
3rd grit=400
last grit=600(or even 800 if you're picky)
start off with the 240,going pretty agressive(within reason
),ultimately
ending with the lighter grits,sanding less and lighter with each grit.
each grit should almost erase the scratches/swirls/scrapes from the last used grit.
once you finish up with the 6 or 8 hundred grit,then hit it with the plastic polish to bring back the stock shine/gloss to the plastic
(some automotive polishes will work too,but make sure it's "fine cut" polish.)
