since @stugray so eloquently put out the reality of performance gains, what are you really sacrificing when you touch the clutch/FW to make the driveshaft a must-do if one was replacing the former?
Like I said in the prior post, if you have the JDM underpannels and go through all the work to unbutton the bottom of the car to get access to the trasmission, you might as well change the driveshaft while you're in there, if you're after the weight savings. You could do them seperate of course, but using basic tools you add another hour or so of busywork just to get back to the area you need.

As far as the rust, of course surface rust doesn't matter, but it turns into actual concerning rust fairly quickly; my stock exhaust flanges were starting rust severely to the point of effecting function after just two winters. I hadn't originally planned to do the driveshaft at all, but going down there for the flywheel and clutch and seeing it with spots all over, I figured I might as well gain corrosion resistance and drop 10 lbs for relatively cheap.
