5-15mm either way (especially shorter) is unlikely to cause any problems with mis-matching with your cylinder.
If you're dead set on a certain length...then an option is to custom cut one. Doing it on a lathe is the best way to do that. It's also best if the material is brass (cuts really easily and cleanly) or stainless steel (harder, but can be cut and finished nicely).
Bore up parts are not needed unless your inner barrel is very long.
Silent head systems, sorbo setups, etc....are up to you. I like the Silent setups....many prefer the Sorbo setups. Regardless...buy main line brands....element/clone parts suck ass.
