Hey Mike,
If I were you, I would keep the mirrors and rear spoilers the way they are now just like the original TypeR.
There is nothing wrong with the way it looks and I certainly do not think the black mirrors and CF spoiler belong to your car. To add these to a first generation TypeR would transform a very clean looking TypeR to a 02+ R wannabe. Many people like the black mirrors and CF spoilers because those are what the new R has as OEM but I don't think there are necessarily better looking. IMO, if you start out with an original headlighted car, you should keep the color scheme consistent with the old Type R. By all means, if your car is an 02+, then the black mirrors and CF spoiler would be very nice. I just don't think the extra effort and money to put those new Type R's mirrors and spoiler would look better than your current set up. As far as the 02+ wheels, I again don't think they look any better than the 94+ wheels. I would much prefer the rear to be 18" to conserve that staggered look. That set of 02+ white on your car look out of balance. The front has the illusion of looking bigger than the rear. I think you have started with a very done car. All you need to make it to look mighty nice is a set of white 16/17 with spacers front and back or a set of painted white GC07s.
