I fixed the "facebook photos in the Gallery" problem first by removing my facebook account from the Social Networking app. The trouble is, the only really useful part of having an account in the Social Networking app is sync'ing your facebook contacts with your phone contacts - which I happen to like. The Social Networking app account provides content for other things too (i.e. Gallery, the widget, etc.). My final solution was to remove the Gallery (rooted) then install Quickpics. Problem solved. MotoBlur apps really do suck.
