The Doctor has always held a sort of "snobbiness" towards the human race. It was very evident in the earlier episodes of the series. He really is a rather crotchety know-it-all. Different incarnations of the character brings different pov's, but for the most part he does think himself superior. I believe his attitude in earlier incarnations might shock you, but then we're talking about someone who is probably something like 900 years old or more at this point and has traveled back and forth and sideways. So he's actually in character with the original concept.

As for Rose..yeah. I like Rose, but she did become too absorbed with the Doc, to the extend of shutting everyone else out. I think that's one reason her story ended, and that it ended like it did.
