I thought the same thing about the confrontation in the woods. That they were still acting like Wraith, even in human form. That would have been far more awesome and unexpected. Oh well.

And why on earth was Carson wandering in the woods by himself?? Stu-pid!

I'm ambivelent about them killing the Wraith-humans. Their plan clearly wasn't working and I can't see how they could have successfully integrated them into normal human society. They also couldn't leave them alone and risk them escaping. Still, I understand Rodney and Carson's instinctive reluctance to killing all those 'people'.
