The name-changes the mod makes is only to objects it modifies. So it might for example change the name of the creatures you are replacing, or the weapons etc.
Installing the mods is quite easy, you just go about it like any other mod.
I understand russian but I can't download the mods now to tell you how to install them, but there is no real mystery on how to install them. Just go about it as if you would with a normal mod.
Although be advised, the russian mods will give the objects that are changed funky names, which you might want to edit in the CS, so that they are in english. Good luck
If you still need help with installing I'll look into it after I get back from work
