Hi, thanks for your report.
To the first issue: This appears to be possible with vanilla as well, so this is not a far-reach specific thing, but possible in general. Still interesting though.
To the second: Yeah, when there are multiple mods that override character reach, the one with the last write wins. Not much to be done about that. In theory, I could override the reach settings more often, but in the end, I don't see a foolproof method to ensure that far-reach always 'wins'. As you said, you can just go the mod settings (afaik, you don't have to change any value, just confirm), I hope that's not too much of a hassle.
