Did you use directly-allocated buffers? Did you set the buffer positions to 0 if added to them after constructing? I didn't see a projection in your list. What are you doing to set it up?
When texturing use GL_NICEST as the perspective correction hint or it'll distort when not at 90 degrees to view Your UVs don't appear to be correct, as they start in upper left and your quad starts in lower left. That will produce a rotated image - shouldn't be what you describe. Could you show us the texture and then a screenshot of the bad rendering?
