Do tapes recorded with all those features gracefully degrade to be playable on regular tape-decks, or do you need a decoder module for them?

If you do need a decoder, why not just use the tape as a digital backup tape, and write a high-bitrate FLAC file to it? A decoder is a decoder.

HX-Pro is a system to automatically adjust the bias level when recording, in order to increase headroom. It is only needed on the recording device, and improves playback quality on all tape decks.

Dolby B/C/S is needed on both the recording and playback decks, as it changes the frequency response to boost high-frequency sound quality.
