Mine was completely worn out and slipping. Car could hardly move so I think you're doing the right thing by changing it while it is still driveable before you get stuck at the foot of a hill.
As a bonus, I think you'll find the new clutch will be a lot lighter and have a nice over-centre feel in its operation. I didn't change anything in the hydraulics and noticed an improvement in lightness. Then I bypassed and removed the damper - an easy job at any stage, it's bolted to the air filter mounting bracket and the hose fittings are interchangeable with those on the slave cylinder - and the clutch became much smoother to control. I find it easier to have my leg control the engagement rather than some fluid-flow-restricting device that seems to make the engagement more jerky, the opposite of its intended effect
I think the original damper could have worked in some particular high-revs sidestep-the-pedal scenario, but in normal driving I found that it was out-of-sync with requirements and removed the 'feel' from the pedal.
