They definitely had the barrels of pipeweed in the extended versions. I can't remember if they were in the cinematic cut, though.

And yes, yes you do. You make things into Things.

I have vaaaaague memories of Oropher maybe being obliquely referenced somewhere, but they could have been appendices or something. Tolkien focussed more on Celeborn, but I think there was a sort-of mention of them falling out over Galadriel or something. I don't even know anymore. Tolkien wrote so much!
