8s,
Can't help with the jetting advice off the top of my head, but as for the brass bits, general consensus is only use OEM. Unless something is obviously mangled or waaay corroded, you probably won't need to replace what you have if it has been properly cleaned. There are issues with other manufacturers (like Keyster) where the orifice sizes,etc aren't what they say they are.
As for the settings, look in the faq at the carb section #7 reply and there's a graphic hat has all the original set up with jet sizes, needle settings, etc. link below.
