1) Yes for XP. With Sims 1, if you don't have either a) Complete Collection or b) Unleashed, Superstar, or Makin' Magic, you might want to use Win98 compatibility.  For Sims 2, it should be no problem.  I've heard someone elsewhere mention running Sims 1 under Win 7, but don't know details about how to make it work.
