Should I trade Roddy White for Arian Foster?

I absolutely would not. I don't understand the fantasy infatuation with rookies who have not taken a real snap in the NFL i.e. Foster, Mathews, Spiller, Best. I would not give up a WR you could start every week for a guy who hasn't proven anything, including that he can keep the starting job. You're definitely deep enough at WR to take a risk, though. I would just go for someone who will definitely be getting carries. As far as Barber/Jackson, I would probably not do it. I think they are pretty even, but Barber has a little more upside because he plays on a better team.
