Fender bumper gap is because your using conversion fenders. Seriously you don't want that gap, it ether takes a lot of work or steel fenders. My car is steel fenders. I used a s14 zenki bumper support and the stock s13 radiator support. I also welded on custom tabs for the fender support because I did not have a S15 upper bumper retainer at the time.
pics of my car no gap and oh I see the same situation with your carbon fiber hood I have with mine and yes I painted the Carbon Fiber.
Your car does not look bad though for conversion fenders. I have seen a lot worse. LOL
pics of mine below.
