Rotate a vector

Hey, I''m working on a way to position moveable objects in a FPS game, and I would like to know, how to rotate a vector with the parsed in quaternion(0 <- x, 1 <- y, 0 <- z, 10 <- angle). I know it propably would be faster to create the object in object space and just use glTranslate and glRotate for the movement, but then I can''t use it properly with collision detection and per-pixel lighting.
