Sinosauropteryx is the most PRIMITIVE feathered dinosaur found.  However, it (and all the other Chinese non-avian dinosaurs with feather impressions) are from the same formation, which is Early Cretaceous (Barremian Stage).
 
Archaeopteryx is the stratrigraphically oldest fossil with feather impressions.  However, phylogenetically it is closer to modern birds than the Chinese non-avian dinosaurs.
 
 
>And does any one have any pictures of the feathers/dinofuzz that was found on Beipiaosaurus  inexpectus

A quick websearch found the following link, which has the whole original paper (figures and all) up on the web.  Don't know that they have permission to do so, so check quickly before it is shut down...
