So that hydraulic line that arches over the manual transmission (it's a 190 trans). It has a rubber section on the end. Is that a one piece part or is the rubber part replaceable alone? Should I preemptively replace it?

I would tend to say yes, replace it if the cost isn't exorbitant. It's like a flexible brake hose, and we know those go bad with time. If you're in deep enough to have to bleed the clutch, you might as well replace all the items that wear or age. Just my $0.02.
