Revolution is an Interface Development Environment developed on itself.
This means that the whole interface which allows you to access the 
engine is made of Rev stacks.
That is powerful : you can modify your own development environment.
For instance, Ask and Answer dialogs are rev stacks (they are exactly 
stacks as yours).
To be more precise, they are substacks of stack "Home" whose file name 
is "license.rev" in Rev folder on the desktop.
But, PLEASE, wait to be familiarized with those notions before acting!

> What does it mean to restore one?

When you use ask and answer commands in a script, Ask and Answer 
dialogs stacks are called by the engine.
If you modify these stacks for your own purposes, you will restore them 
once the modified version has been included when creating a stand alone 
(.app or . exe).
If you don't restore them, you will never find again standard dialogs 
in the IDE, in the others stacks you will receive or create!

I don't think so:
These dialogs are modal windows, ie once called, you can't do nothing 
but wait :-)
All executions are blocked until the user has clicked any button.
This is the reason why you have to modify the programming of the dialog 
stack itself (which is transcript handlers and functions as in your own 
stacks).
If you accept a piece of advice to begin, have a look at Rev docs, 
especially to "Main stacks, substacks, and the organization of a stack 
file" and "Windows, palettes, and dialog boxes"; all that in the 
"Topics" section.
Hope this helps.
