Fill display is confusing and inconsistent. Until it gets tidied up, this is all I can tell you.

"Labels are text blocks or symbols optionally linked to construction elements and 2D fills. Labels allow you to identify or comment elements or parts of your design." That's from the ArchiCAD 9 Ref Guide page 343, and it's pretty succinct so I'll keep it. Here's more:
"You can use labels in two ways:
• Independent labels manually placed using the Label tool.
• Associative labels can be assigned automatically before the creation of an element or added to them later."
So there's two kinds. Independent labels are like regular objects, in that they do their own thing. There is a simple text label that's basically a text block with a leader, and it works OK as long as you don't go longer than one line. I (used to!) use these to call out structure in the sections and other simple things like that. They are a marginal improvement over plain text with an arc.
Associative labels are attached to elements, and can say intelligent things about them. They remain accurate as the data they represent changes. They can move when the element is moved. They are very cool.
(Why don't we use them yet? Because the underlying design of the label functionality is very poor, making it hard to figure out how they work, especially the differences between the two kinds. Now that I/we have them figured out, the actual making isn't hard.)
Frequently (Probably) Asked Questions follow. I'm focusing on associated labels, since independent labels are simple.
Zones are calculation instruments. They represent rooms and other definable areas/volumes in the project.
Nothing new really, but here's some links to the stuff we looked at.

Update: I have expanded on this topic here". I have strikethrough'd the really wrong bits here.
(I am planning a tech meeting for this topic the week of the fifth.)
Q What is a detail window.
A new kind of window in AC8. A hybrid of a section window and a patch.
Like a patch, they can be generated from existing geometry. Like a section, they can be renewed. Unlike a section, they cannot be model views, only drawings.
Q What are they for.
