My first guess would be a bad wet clutch, especially if you're not sure what type of oil is in it. Be sure when you put it back together to use wet clutch rated oil. JASO-MA rating I believe. As for the clutch faces, it never hurts to scuff them up with some scotch brite. As far as I'm aware, it won't hurt anything if your one way fails, but you will lose engine braking. For sure you want to replace it though, instead of leaving it bad, because it may or may not ruin something else.
