Bandolin, I have class this morning, but when I get back later, I'll address some of these models.  Particularly we can discuss the way to avoid ngons, and create the spout on your model seamlessly (or at least as seamless as I can get it).  The key there is to create holes first. , before the subdivision, then extrude the edges.  You can avoid distortion by making the holes planar before extracting edges.  I'll show an example using your model later.  Gotta run for now.
