Currently, the instructions on getting LilyPond up and running in a terminal on mac osx have the user create a script which calls the lilypond application, and then add the location of the script to the $PATH. Is there any advantage of this over just having the user add the location of the lilypond binary to the $PATH?
They are different: has other stuff in it than just the lilypond programs, for example ps2pdf. If one adds this location to the environment variable PATH, one must decide which version of these to call.

From a user's point of view why is it done like this? Why have two 'bin' locations and not just put it all in

I'm not sure what you have in mind here. On BSD systems, like Mac OS X, /usr/local/bin/ is the traditional location for user installed UNIX programs - they typically end up there when doing 'make install'. Apple added /Applications/ to make sure these are not confused with those; they contain a UNIX program, of course, but are otherwise "bundles" - directories containing a lot of other resources.

Among the resources the LilyPond Application adds are some UNIX programs it uses. The idea is to get the right versions. In fact it doesn't: guile will call the stuff /usr/local/ even if LilyPond has its own stuff. So I have to go into the Terminal and change some library whenever I want to switch between using my Guile in /usr/local and lilypond.

But one could add /usr/local/bin/ before the Lilypond directory. In addition, I have paths to MacPorts /opt/, Fink /sw/, and TeX-Live / usr/local/texlive/ TeX.

After my problems with getting Mac OS to work in Terminal (I just needed to RTFM) I noticed that I had a .profile in my own account, now I know that default users (admin or otherwise) do not have a .profile so I must have created it ...

As James Bailey pointed out, the package managers may add it - though I thought it was Fink; perhaps both do.
