You are actually asking all personal preference questions. If your Kimber is 100% reliable how could it be made more so? It is really up to you to decide if you need new sights, ambi safety, new beavertail, some sort of grip enhancing (checkering, serrating, scallops, waves, conymids, etc)
My personal tastes don't suit everyone. I like the idea of hard chromed stainles guns with ambi safeties (lefty), Hennie straight eight sights, ground mag well. Add some 30 lpi checkering, scallops, or maybe a soft wave pattern and you have just about my ideal gun. Ohh yeah 4 lb short trigger with all tool steel firing components.
So the real question is what do you need? Not what would we like to see you have.
