I typically got a little burning clutch smell, but pretty minimal. I wouldn't change the clutch out yet, especially given that when you adjusted your cable things were a little better. My clutch took up to 3k miles before it behaved more like the stock clutch (less noise, better driving dynamics). That being said, it still does make more noise than the stock. The break-in period is critical for the clutch. The exact number of miles you need for break-in varies, from experience, my number was 3k. Don't drive too hard on it- it will grip just fine but it will be better in the long run if you don't drive hard. It may temporarily solve the problem but you need more miles on it.
I agree with trinity_gt that the problems in reverse are weird and may represent mounts or some other issue.
