Well the thing that bothers me the most is that Unknown Regions take almost entire left half of the galaxy. And even more so that they span almost to the core.
It's not really half the galaxy, just the "northwestern" bit. I see what you mean, though.
I mean I do not know know which EU author actually mapped the galaxy. I think he/she is the one to blame. Well it is true that Unknown Regions appeared in KOTOR game and other sources but they never determined its position and size.
The earliest map for the whole galaxy I know of first appeared in The Essential Chronology, published way back in 2000, which predates the KOTOR game by several years.
Mention of the Unknown Regions predates that book, though, and I even think the second book in the Hand of Thrawn duology describes the Unknown Regions as being a lot larger than they're shown to be in that map.

I wonder if dark energy, dark matter & black holes fit into the Star Wars galaxy
If you're going by the EU, then yeah, those things exist. There's a cluster of black holes known as the Maw, and some blather in the NJO books mentioning invisible dark matter galaxies that interfere with hyperspace travel to areas outside the galaxy or some crap like that.
