Well there's some stuff I didn't know. Probably because one source was a kids' show and the other is a series of books I've never seen. I think I stumbled across the two droid species' pages once, but didn't pay much mind. I don't remember the Cremlevian War, though. It sounds familiar, but I don't know if I heard of all the bits of history in it.
Some of those mysteries have been explored already although not really in much depth. The two droid species are implied to be the Silentium and the Abominor who fought a war without any regard for the native organic species of the galaxy (although I don't really know if you could call it a war when one species can dstroy Imperial cruisers and the other is foiled by R2-D2 and C-3PO, although they did bring down the World Devastators....).
As you mentioned their living homeworld gave them gifts and they fought back, driving both species from the galaxy. However the sweet taste of victory led them to pursue a violent crusade to purge the galaxy of all technology, resulting in the enslavement of several cultures and the extinction of others. Eventually, with much of the galaxy under their control, they turned on each other in a brutal civil war that destroyed much of the galaxy including their homeworld. How this happened is unknown (probably the Y'ogand's Core tactic).
It was known that the war ended due to Y'ogand using this tactic to slay Warmaster Steng, but the galaxy was left in ruins and when Yuuzhan;tar was destroyed the symbiosis they shared with the planet resulted in them being cut off from the Force and them constantly experiencing pain (a phenomenon they interpreted as some kind of penance). Regardless a bunch of dead planets and debris fields leaves little room to kick your feet up so they were forced to look elsewhere.
That's basically all the known history. It definately needs more expansion in future, although their own history remains largely unknown to them anyways. Maybe some novels set in that actual era would work.
I'm hesitant to agree on the Abominor and Silentium being the direct cause of the Vong though. For one, like I said, those are obscure references, and one of them is quite questionable (Being that it's a kids' show and all), even if everything meshes together decently. Partly because there's this quote by Harrar:
It mentions one race, and that it was more technological than animate. That kind of wording makes me think of some sort of cyborg (A la the Borg, of course) than droid. Some sort of race that evolved to the point that it began to replace itself with robotics, which could also explain the Yuuzhan Vong hatred of technology. Rather than a long-dead memory of invasion driving it, it could be a reminder to them that eventually technology could overwrite life. To a completely organic civilization, that could be rather scary, especially if the cyborg had tried to assimilate the Vong and Yuuzhan'tar, much like the Borg do as well.
The ancient texts are unclear. It appears we were invaded by a race that was more technological than animate. We called on the gods for protection, and they came to our aid, providing us with the knowledge we needed to convert our living resources to weapons. We defeated the threat, and, empowered by our victory, we gradually became conquerors of other species and civilizations.
The same could be said of the Abominor's harvesting of all life to power itself, of course, but that reeks more of sacrifice to a greater being, which the Vong do for their gods on a constant basis. It seems like they would loathe to imitate such an act of a mechanical being. And the mention of one race, and animation secondary to machination, could just be from the historical confusion they were left in.
But these are all just the theoretical musings of a poor little fanboy. Such is the reasoning I think they could set novels and/or graphic novels in that era. It would clear up so many things.
As far as Yuuzhan'tar goes, it could have been attacked by one of the many technological civilizations of their galaxy that came under attack, rather than it being destroyed by themselves. I would think a society so reverent of their own planet would avoid conflict towards it. Unless, perhaps, the planet exiled them, and they exacted vengeance on it.
