Should I trade away Dwayne Bowe and Miles Austin and Thomas Jones?

I would say no. Dwayne Bowe is playing as well as anybody right now, and you just don't know how Vincent Jackson will react. Also, Bowe is Cel's sure #1 target, and you don't know if Jackson will be for him. Barber isn't as good as any of the others. Hillis is good, but not worth trading away the guys you're talking about.
