Like Danny I'm a bit confused, but I'll take a guess. Try double-clicking your texture file in hypershade. (file, ramp, cloud, etc) There is a 2D placement tab or 3D placement tab at the top of the window that pops up. You can adjust the translate, UV repeat, and a host of other things in there as well.

As for the Set, I'm guessing you're talking about a quick selection set. Open up the Outliner and look for it there. Delete it.

Hope I helped out some. Probably not.........
