You should be able to remove the anodizing with a dip in stong oven cleaner. The surfaces of the hub will get all fizzy and hazzy, and then you can sand the remains off with sandpaper in water. Use gloves and glasses because you'll get it in your eye (ask me how I know)
You can also do it with only sandpaper and wet sand the entire thing starting with 120 grit and working up to 900 or 1000, or even 1200...the finer you sand the deeper the luster when you polish it up with a paste like meguiar's aluminum wheel and mag polish (automotive).
Regardless of which way you approach removing the anodizing, you should disassemble everything and have only the hub shell when you wet sand or dip in oven cleaner. I am not familiar with those hubs, but they should be totally disassemblable.
As for spoke hole diameter I would have to say if it changes it will be microscopically. I oven cleaned, sanded and polished my formula hubs and didn't really notice a change in the spoke holes, but I wasn't really looking for it either...
