Probably a little late now, but according to the FSM the clutch slave cylinder, master cylinder, and interconnecting line are meant to be installed/serviced as a unit. I know that you can purchase them separately or complete. When I had hydraulic issues with mine, I wasn't sure whether I had slave or master cylinder issues (and I figured both had 130,000 miles of use) so I bought the whole enchilada, and it came with new fluid installed in it and pre-bled. All I had to do was bolt it in. If I had it to do again, I'd do the same.
