You won't notice the difference between a standard B-17 and higher end Team Pro.
An expensive track crank is no quieter than a cheaper single speed crank, which of course come in 165mm length. My IRO crank, EAI cog, and SRAM PC-68 chain are dead quite.
I ride every day on Formula hubs laced to Open Pro rims over nasty cobblestone streets. I weigh 85kg and usually have an additional 12kg pannier on my rear rack. My hubs are smooth and have yet to explode.
As for stems I've can't tell the difference between a cheap one and an expensive one as I don't race professionally, I ride in the city. That being said I use a Nitto stem as it lets me have my bars higher.
Do whatever you want, but it sounds to me like you've drunken the Kool-Aid as far as thinking that high-end track specific parts will make a difference when riding on the road. They won't, although they do make a difference for the experienced racer in a velodrome.
