No problem. Thanks for your interest. See below:
1) No they are not anodized. Most people that want these want more of a polished look and clear anodizing dulls the finish so I've decided not to offer them anodized. I'm not really in the position to do one-offs on this as I would have to pay minimum lot charges of more than $50 (which I assume would be cost prohibitive for most people). You may be better off clear coating them or having them clear anodized yourself.
2) Depends on the pic your referring to. The XB models are roughly .75" and the 1125 rear sets are deeper to account for the contour of the swingarm. As stated in #1, I'm not in the position to offer one-offs at this price so I'm sorry, I can't make them thinner for you.
3) Yes. I now offer slotted rear sets for the XB.
4) All configurations that I currently sell are $90 shipped to the continental US. As stated before, the natural finish is not anodized at this price.
I hope this answers your questions. Let me know if I can help.
Thanks!
