It does appear that the Mac installer is not yet available. There is  
such an installer for Python 3.1.2:
<http://www.python.org/download/releases/3.1.2/>
if you can live with the previous version.

That sounds plausible, but I confess I've not tried it. Do you really  
need both 32 and 64 bit versions?
--enable-framework is essential if you want Aqua Tcl/Tk (it might be  
the default on Mac OS X, but I prefer not to risk it).

I think you are misinterpreting the README. In the past whenever I  
have built Python from source it has used my own Tcl/Tk (which is from  
ActiveState). I would be very surprised if that has changed.
