Yeah give the super white a go, they are cheap and will do the job nicely, but be prepaired it wont be a match to the LED strip but much better than the yellow glow.
As for the interior, a friend of mine sorted out my paint job while it was in having the wheels done, he was a bit worried abit about pulling apart a new car lol It does give the interior a nice finish but a little more care needed but then its a weekend only car so not the daily drive and wear and tear that goes with it...
Get all your kerbing out of the way in the early stages then look at changing colour while having them repaired
As for the tail pipes, from the very beginning I used a couple of coats of Chemical Guys jetseal 109 to put a protective layer that helps all the crap just wash off, but if you have a build up of carbon I say use some silvo to remove first then some protection like the jetseal.
