Hello M8
Camera movement is a pain in the... back indeed.
As for moving entire room, that my friend is a titanic task, you'll be better off trying to keep your hand very still. You can move an object, you have to use the script function (getPos and SetPos, look in the GECK Wiki) but thats rather complicated, you can also use "rotate" function to rotate object, but those functions works mostly with "movable static" object and even then they only rotate around one of their own axis.
To create smooth movement of ENTIRE room filled with stuff... You could try to convert entire room into a SCOL object (I am, however, not sure if it will move/ rotate) using Xmarker as a first ref (to make this "X" point an axis to rotate around it) If you'd like some help with this conversion, let me know, I battled with similar problem in my mods before, so I may be able to help you out a bit. No promises for success, however. This is a difficult task and I am not sure if it's worth your wile, just let me know If you're up to it.
