Well... were supposed to sort of take a "monolithic culture" idea away from Trek. Overall the ideals of humans are all supposed to be, by and large, the same.
IIRC, the Rodzhenkos lived on a Russina colony before relocating to Earth at some point.
The modesty issue may have been Worf's alone and not a reflection of either upbringing from his parents or something inherent to Klingons or Klingon culture. (I suspect Klingons wouldn't have much issue with being naked.)
It's possible some people still just have a "natural" modesty instinct that's not overcome by the culture. Remember, Worf was very repressed and controlled compared to even other Klingons.
