Personally, I'd say you should have only gotten the window visors. Not only are they more practical, I think that they look a hell of a lot better than those chrome pillars. Granted, I am a bit biased because I hate chrome and would've bought the visors over the pillars any day, but to each his own.
However, since you already ordered the chrome pillars I'd say skip the visors because I think the pillars would look worse with part of the visor covering them.
So, in conclusion, IMO I would say stick with one or the other, don't mix the two.
Obviously though, as long as it pleases you, do whatever with the two, it is your car
