My youngest boy will be 3 this week, so he's close in age to your 3 yr old boy. This youngest boy of mine seems to be completely "normal" (which is such a delight and relief after what we've been through/are going through with our oldest two boys!). I just wanted to reassure you that many of the things you said about your 3 yr old seem pretty normal. Resisting getting dressed, resisting brushing his teeth, still wetting in pull-ups at night, loving dinosaurs, robots, trains, Buzz LightYear, and washing machines, saying things over and over, talking constantly, and asking you to repeat what he's saying--that's all pretty typical of this age.
It's really great that he does so well at school. A lot of boys this age can't handle it yet. You said, "I guess most PDD kids do not interact w/ other kids?" Well, some do and some don't. Some love being around other kids, and some avoid people at all costs! But when they do interact with other kids, their social skills are lacking. For example, they may not understand basic social rules, they lack empathy or understanding of other's feelings, they don't show appropriate expressions or emotions in various situations (such as showing distress or affection way out of proportion for the situation), they have trouble carrying a conversation or even responding to a simple "hello", they might avoid making eye contact, etc.
