You should not change this:
<globalization culture="auto:en-US" uiCulture="auto:en-US"
the rest of your changes are ok but do not change that. The reason is the default there must be a complete tranlsation with no missing keys or it will create errors.
The other settings are sufficient to make it use Russian by default but it still must fall back to English for keys that are missing in the Russian resource files. We have only a partial translation for Russian.
Hope it helps,
