Its normal for the kick leaver to be free wheeling when the clutch is pulled in. That's nothing to worry about. Lunging with the clutch pulled in and in gear is something to look into, I've never tried it.
Since you are planning to replace the clutch, go ahead and do that. Pay close attention to adjustment. Let us know how it goes.
P.S. I must not be too far from you. I'm over on the BC end of Verona road. Maybe see ya around town sometime!
