Well, even before the GdalTools plugin update, it should work with only the GDAL path I gave.  The updates to the plugin were meant for an all-in-one QGIS, where external python programs don't know to look inside the QGIS app for modules.

The real problem is that your GDAL install seems to be messed up.  When installed, it changes the shebang at the top of all the GDAL python tools to use an explicit python version (2.6 for Snow Leopard and 2.7 for Lion) just in case a user has installed a different incompatible version of Python.  Somehow your GDAL python tools got the wrong python version.

What does this return in a Terminal:

file /System/Library/Frameworks/Python.framework/Versions/2.7/Python

It should be "No such file or directory".

What does this return in a Terminal:

ls -l /Library/Frameworks/GDAL.framework/Versions

Forcing GdalTools plugin to use a user-installed Python 2.7 on Snow Leopard with the Python 2.7 version of the GDAL module may work, but I don't support that in my GDAL framework.
