About as much as a flea running into a semi on the highway.  These 
papers have more holes in them than a decomposing reptile...

No, although if you're less than ~200kg it's harder to maintain a 
strict temperature range if you aren't insulated (doesn't have to be 
feathers; fur-like structures, blubber, etc will work too).  The 
evidence is overwhelming that most coelurosaurs and all maniraptorans 
in that size range were insulated, but it may well be that other small 
to medium sized dinosaurs were not as good at maintaining a narrow, 
placental-like range of body temperature.  Behavior can help mitigate 
this to some degree.

As an aside, must dinos have been feathered to have been warm-blooded?  
Even in
warmer climates?
