- multiple paths ARE allowed mostly everywhere where it makes sense (all emu "search paths" and image folders/files at least)

- you can specify -config_path on the command line to change the "local" config path, otherwise it's auto-determined for good reasons, and "portable installs" are fully supported

- you have to specify paths in a POSIX-compliant way ("auto-correction" would mean to guess what the user wants, and that's plain wrong)


QMC2 supports the codecs you've installed, so basically yes.
