Agreed with most of this list. Two remarks:

I don't think perl's threading is all that interesting (except when interfacing with threaded C/C++ code).

Multi-process (forking/IPC) code is more useful just because it's more general (and also easier to translate into multi-machine/networked code), and because of that I'd recommend POE as a good framework to lean since it really makes IPC, networking and event programming a lot easier.
