You can determine approximately vintage by applying some of the information contained in
How Old Is My Bike? As for how good is the bicycle, clues to its quality level will be shared in
Bicycle Quality.
Can't help much with anything else at the moment. I might suggest, however, that the OP, that's you Shaynethelazer, post good clear pictures of the bike and close ups of frame and component details. Doing so will likely result in much better feedback from other forum members.
