We''re simply other users like you, so your last sentence will have no effect.
If - and I stress if - you were able to re-install iTunes 10.4, your iPod may not work with it if it has been set to work with a later version. For that reason, going back to a previous version of software is not recommended.
But I have to ask, what exactly are these features you don't want? Can't you simply ignore them or not use them, which would be far simpler? Or change the iTunes interface to whatever it is that you want?
