Build tactics, and a tactical development case question

Build tactics, and a tactical development case question

Background: I'm in the process of ratcheting-up my involvement with
jQuery-UI testing, documentation, etc, Since I have a potential
development case here, I need to be able to build the latest to create
a coherent js package for the development case.
My js development environments are Windows and OS-X.
Question 1: I should use Ant, not Make, correct? The jQuery developer
docs also refer to Make but I haven't seen it referred-to here.
Question 2: My primary interest in this particular development case is
replacing the current Filament Group-style fg-buttons with the formal
ui-buttons actively being developed right now. What's the feeling,
will buttons likely make-it into the 1.8 release?
