Very little of the above information is useful in identifying the bike. What brand/model of tubing is it made from? There should be a sticker right above the shifter bosses, the annoying things sticking out from the downtube.
At this point there is no way to tell what is original, if anything, to this frame and what isn't. The bars, stem and seatpost may be original but would point to a lower end model.
