Try this package for both multiplexing a mkv file and extracting streams.
This should be the only option. MKVtoolnix will very easily (and with a GUI) extract the streams from the MKV container.

Just tried MKVtoolnix. I'm still running into the problem that Adobe Premiere will NOT import the extracted files. I now have an .h264 and a .dts file. These are not supported. Basically I'm looking for something that extracts and converts both video and audio to something that I can use in Adobe Premiere without losing (a lot of) quality. I'm not sure if something like this exists.

Well. I figured it out. Used Tsmuxer to put the whole thing into a .ts-file. Hardly any quality loss there (maybe none, not sure how this works, just going by eye). Then I found a freeware program to convert the original mkv to an mp3 (320 kbps). That'll do. Still it surprises me it's so hard to find a piece of software to do all of it at once with a bunch of presets. Should be possible.

Why? Premiere is for video editing/encoding, and both H264 and DTS are already encoded. It's expecting uncompressed formats that would be straight out of the input device (e.g. RAW video, or WAV audio) so that any manipulations wouldn't incur a further quality loss.
