Minor correction: the Danann didn't take Ireland from the Fomorians, they took it from the Firbolg. The Fomorians were a group of pirates who tried to take over from the Danann, and were defeated at the Second Battle of Mag Tuired. I got mixed up, sorry.
I was in a hurry when I passed through here earlier, but I can respond now.

Be interesting to see how they decribed these "Gods" and compare it to what we know now.
I don't have the original sources with me (they're in the library's reference section and I can't take them out), but I have a page of notes, and the Danann turned up (not literally
http://www.xwingalliance.com/forums/wink.gif) ) in an Irish course I took last semester.
The Irish legend describes four artifacts that the Danann brought with them from "four mighty cities to the north:"
The Stone of Destiny, called the Lia Fбil came from "Failias," and would resound or vibrate when touched by one of royal blood. The only analogy I can think of is some sort of genetic scanner, able to identify someone by their lineage. According to one legend, this is the stone (imported to Britain) that Merlin put Excaliber into before Arthur ("Artus") claimed it. A boulder identified as the Lia Fбil is currently underneath the throne (in a compartment) at (IIRC) Westminster Abbey.
The Spear of Lug (or "Spear of Light"), called the Gae Bolga, came from "Goirias." Based on the descriptions, it sounds like some sort of hand-held artillery weapon. The only accounting I can give is a long-barelled rifle, firing explosive ammo. The book notes the similarities to Zeus' lightning, so it's possible these might've been a fairly common weapon. The mental image that comes to mind are the Blast-Lances in Stargate. The Gae Bolga eventually fell into the hands of Cuchullain, the ancient Irish super-hero. Current whereabouts unknown.
The Cauldron of Dagda, called . . . the Cauldron of Dagda (*shrugs*), was a cauldron of food that would never become empty. The only analogy I can think of is one of Star Trek's replicators. The Cauldron came from "Findias," but its current whereabouts is unknown.
I don't have any notes on Nuadu's Sword, except that it was very sharp and strong, like Excaliber. Nuadu (the Danann's leader) brought it from "Muirias," and probably lost it somewhere in Ireland.
In addition to these treasures, individual Danann also had specialized gear.
Dagda (in addition to his Cauldron), carried a magic harp, upon which he could play songs to work magic (like Link's Ocarina in Ocarina of Time). Most famous was the Song of Sleep, that would make any who heard it fall into a deep slumber.
Mannanan (sp?) had a cloak that would turn him invisible, as well as a chariot that could travel over water. The chariot might've been a hovercraft, but I can't account for the "cloaking device."
Nuadu, the ruler of the Danann, had his hand cut off in battle (after arriving in Ireland), and had another Danann (who's name escapes me) craft him a prosthetic out of gold (or bronze, or brass, depending on the legend and the translation). After this, Nuadu was known as Nuadu of the Golden Hand.
I'd be willing to accept that the Danann, if they did come from Babylon, might've brought technology close to or equal to ours, but I still can't reconcile the Lia Fбil, Dagda's Cauldron and harp, Mannanan's cloak, or Nuadu's prosthesis with technology the Babylonians would've had access to. (Remember as well that Nuadu's golden hand was made in Ireland, not brought with them.)
