As for the noise, thats just how this transmission/drivetrian is. If you let it idle you can here chatter coming from the tranny. you could try using readline tranny fluid and that should help it run quieter:

Redline MT-90 1 qt (manual transmission fluid)

you can also try to change out the diff fluid also.
