Only if the wheel wasn't built properly. I constantly bomb stuff on my fully rigid SS MTB that is far worse than any urban environment ever dishes out and my wheels rarerly need to be trued. If I true them twice a year that is out of the ordinary. Even when I flat spot or dent a rim I barely have to touch the rim. The fixed gets thrashed on the streets, bunny-hopped, jumped and even taken on the trails sometimes and it holds up just as well.
As for the chain, I frequently lube mine. If you ride your bike a lot you need to.
