Dark Chaos Shuffle & Dipping Shenanigans

[Curmudgeon]

So... is that a yes then on the armor and shield proficiency bonus feats?

That's a yes for those that are explicitly expressed as bonus feats. You're trading away something that has real value but just doesn't happen to fit with your build, and with a real cost (4,900 gp per feat traded).

Edit: Do note that just because the rules allow it doesn't mean your DM will be happy. YMMV.
