Does anyone know what specific parts and from what manufacturer would be considered "approved mods" and wouldn't void any warranty from the dealership?

The safest way is to go to the dealership and ask. Since a lot of dealership offers their own aftermarket parts and as long at they're the ones to install it they should still honor the warranty.

It's an age old question about mods. Each dealer will tell you different stuff as far as what voids your warranty. The bottom line is, if you take it in for a specific problem and they feel your mod caused the problem they won't honor your warranty. It's a nasty can of worms.
