Not by as much as you think, because the dialplan is compiled into an 
intermediate form when Asterisk starts  (and again when you execute `dialplan 
reload`) -- it doesn't have to parse the whole text file for every call.

Yes  (and that's a sensible way of doing it anyway).  Just remember, a 
variable won't have a value until the include statement which includes the file 
with the line that defines it is parsed.
