I've heard various theories about the Ebla tablets, but while this wikipedia article says it might support the stories of the Torah, I've heard from others that it actually discredits many of its stories due to the contemporary nature of its inscriptions and what they might actually mean.
The Ebla tablets are a series of about 1800 full tablets and about 4700 fragmentary texts recovered from the site of Tel Mardikh, also known as Ebla. They provide an incredible amount of information regarding economic processes and international relations in northern Canaan and ancient Syria in the Early Bronze Age (3000-1800 BC).
The controversy came about because the tablets are difficult to read. The claims that the tablets mention Scriptural figures and the cities of Sodom and Gomorrah were based on some erroneous readings and a lot of disinformation that was leaked before the texts were published, which was fueled by Zionist-Palestinian conflicts, turning the archaeological issue into a modern political issue. People were working from unpublished facsimiles of the texts, which made the characters even more difficult to make out.
Modern scholarly consensus is that the texts do not discredit anything in Scripture, nor do they confirm anything in Scripture, rather, they simply exist on a parallel line, providing context to the world without actually touching the people or events recorded in Scripture. They neither discredit nor confirm. Most of the texts are economic records, or dictionaries (actually an extremely important find, as it allowed scholars to refine their understanding of Sumerian), king lists, lists of place-names and so on. Administrative documents. The cool thing about them is they were organized on shelves, and when the building was burned, the shelves collapsed, preserving the ancient organizational system, allowing us to see how the texts were organized and archived (filed, if you will) for later access and retrieval.
