The convention (more used among Unix variants but I guess the same thing applies to Windows if you're setting the system path) is that running "python" from the command line will give you the most recently installed one. If you want to specify a version, it would be "python24" or "python25". Each version of Python is installed in it's own directory and maintains its own path so there aren't any problems with stdlib conflicts.
As far as Windows file associations go, I suppose the most recent install would dominate though you could always reset the associations yourself.
