Do I need to remove the slave cylinder in order to bleed the system? I
was expecting there to be place to attach a hose, and some sort of
valve, but it's just a black plastic cylinder. There's a small bit of
plastic sticking out the top, but it didn't feel like it was anything
useful.

BTW, I've never bleed a hydraulic system before.

that bit should be a zerk fitting.

You sure that the slave cylinder isn't aluminum? Anyway, older versions had
a small port just forward of the hose. It was basically a hole with a
screw you loosened off. The last two replacement slaves I've looked at
still had the threaded part but no hole through to the inside so they had
no bleed capability.

With the external slave, there really is no need for a bleed port - the
clutch master has no residual pressure like a brake master and air will
just bubble up the hose. Sounds good, but if the slave has a slant to the
rear (parked uphill) you can get a small bubble trapped in it. On a new
slave, I like to bleed it before I bolt it in. Hold the slave with the rod
down, push the rod all the way into the cylinder. Release slowly. Check
the master for fluid, then repeat 2-3 more times. No more air. Install the
slave and you're done.
