How would you make the Kech Draguus distinct from the Draelaes Tairn?
The Kech Draguus is a very deep cut. They weren’t mentioned in Exploring Eberron, and I believe the only canon source for them is a Dragonshard article I wrote, which states “Long ago, a rogue gold dragon formed an alliance with a clan of Dhakaani hobgoblins. Now this Kech Draguus has emerged from hiding. With a corps of half-dragon goblinoids and a few full-blooded dragons at its disposal, the Kech Draguus are poised to reshape Darguun.” The Draleus Tairn, on the other hand, are dragon SLAYERS. Dragons of Eberron has this to say: “The Draleus faith holds that the warrior draws strength from victory, and passes this energy to his ancestors . . . and no victory is greater than the defeat of a dragon.” There are RUMORS that Draleus dragon slayers can gain draconic powers and could become half-dragons, dragon shamans, etc, but those are of course rumors.
So, the two are VERY different. The Draguus are a Dhakaani Kech, which is to say, a tightly disciplined military force. They work WITH dragons, and essentially, they’re the Dhakaani answer to the Targaryens; they are going to employ dragons as living siege engines on the battlefield. Their champions may be half-dragons, but if so they were created with the blessing of their dragon patron, who in all likelihood counsels the leaders of the Kech. As the Dragonshard says, they have an ALLIANCE with dragons. By contrast, if there’s a half-dragon Draleus warrior, they gained that power by killing a dragon and ritually bathing in its blood. There’s no alliance between the Draleus and dragons; rather, they are bitter enemies. Beyond that, as Dragons of Eberron calls out, “The Draleus Tairn rarely socialize with outlanders, or even other elves… due to their isolation and reputation, few elves trouble the dragon slayers.” So the Draleus Tairn are at best isolated warbands, and often LONE INDIVIDUALS pursuing their personal quests… while the Kech Draguus are a militaristic, disciplined city-state.

Q: The Gold Dragons of Kech Draguus guide the Kech, but how do they create half-dragons? Do they mate with Hobgoblins there, and if so is it a proper romantic relationship. Could a Dragon of Kech Draguus have a proper romantic relationship with a Hobgoblin. How are the Half-Dragons treated? Are they more tied to the Ul Dhakaan because of the Gold Dragon dream abilities?
The primary source on the Kech Draguus is this article: https://keith-baker.com/draconic-miscellany/ This article states "(the founding dragon) forged an alliance with a Dhakaani city, protecting the city in the waking world and guiding its citizens in their dreams"... So keep that in mind.
Fizban's Treasury of Dragons calls out that "Just as dragon reproduction is not necessarily a straightforward biological process, half-dragons come into being through a variety of means". Now, I could see the idea that the founding dragon fell in love which a Dhakaani champion; it's kind of sweet. Gold dragons are particularly noted as being accomplished shapeshifters, and I could imagine a story in which the dragon spent a period of time with the champion in hobgoblin form, perhaps only revealing their draconic nature when they were to produce an heir. HOWEVER, because this story is tied to the Uul and because of the abilities gold dagons have relating to dreams, there's an entirely different way to tell this story, and that's to say that the romance between the founder and the champion TOOK PLACE IN DREAMS, because hey, in dreams, the Dhakaani champion could be a dragon themself. Again, following the principle that half-dragons can be produced in many different ways, I could easily see the idea that the half-dragons of the Kech Draguus are ALL sired in dreams.
So: I could imagine a truly remarkable hobgoblin and a Draguus dragon having a romantic relationship. But I'd personally focus on the fact that much of that relationship would be based in dreams, because in a dream what does it matter whether you're a dragon or a goblin? You interact with the inner essence of your beloved, unburdened by their body. Again, shapeshifting is an option, but if you spend your time in dreams it's not actually required.
As for how half-dragons are treated in the Kech Draguus, I see them being celebrated champions of the Kech and that great things would be expected of them. And yes, I think it would make sense to extend some of the dreaming abilities of the 5E gold dragon to gold half dragons -- at the least, to make them especially effective lucid dreamers.
