I think the first and third lenses you linked are the same. I wouldn't buy a long lens without VR (I mean IS), especially one that's f/4.5.
I think any UV filter would increase lens flare... I may be mistaken but my understanding is that the more glass between the scene and your sensor, the more flare you can get. UV filter is to protect the surface of your lens and eliminate UV light that's outside the visible spectrum from your photos.
