Sorry for my ignorance but what is the Q hypothesis?
"Q" figures in answering the 'synoptic problem", which is to say, explaining the parallelism of Matthew, Mark, and Luke. If you line the three it's pretty simple to see that almost all of Mark appears in the other two, pretty much in the same order; this has led to the theory that Mark was written first and that the other two are elaborations of the Markan text. Things get interesting when you compare the other parts of Matthew and Luke, because there is still a lot of material in common. In particular the sayings of Jesus (of which there isn't a lot in Mark) tend to appear in both. Germans in the late 1800s postulated another source which we don't have, which they labeled "Q" (for "Quelle", or "source").
At the time the Nag Hammadi texts weren't known. They knew there was a gnostic Gospel of Thomas because the Fathers refer to it, but they didn't know what was in it. When the Nag Hammadi texts appeared, one of the texts was this "gospel", which is indeed unmistakably gnostic. But what was especially intriguing was that much of the sayings material ascribed to "Q" also appeared in Thomas. This led to tons of speculation. The radicalist theory is that Thomas is "Q". I don't think anyone but the radicals take this seriously; it has too many dating problems. A more middle of the road position is that "Q" remained as a separate document to which the author of Thomas referred. There's also a position arguing that there never was a separate "Q".
Except for the radicalist position, none of this has much impact on orthodox Christianity (small o). It's not too hard to read this stuff and conclude that it tends to boil down to people riding their particular intellectual hobby-horses.
