Ok, Totemists were one of the mainly race-restricted ones, correct? What were the other race-restricted ones, or did you ditch that idea?
New mage class being the one you made? With the colors?
A homebrewed warlock, or the regular one?
Allomancy... It seems really cool, but it also seems like that should be a central part of any setting. Maybe if you said it was widely used by one of the nations, or a particular race/ethnic group? Or it's a secret discipline? It just doesn't seem to fit in...
Truenamers... please, fix them. Any of the fixes, but not the basic Truenamer.
Psionics is sorta in the same boat as allomancy. It could fit way better though, if you banned some powers. I like it better in this setting.
And the more homebrewed stuff innate to the setting, the happier I am since I have very few 3.5 books.
