You can install GCC 3.2.3 in complete safety. If you want to install
3.2.3 and overwrite 3.2.2 complete, you'll have to remove the stuff that
GCC left over, which off the top of my head are the following things:

/usr/lib/gcc-lib/*-linux-gnu/3.2.2/ (everything in that)
/usr/include/c++/3.2.2/ (same)
/usr/lib/libstdc++.so.5.0.2 (3.2.3 installs libstdc++.so.5.0.3)

The GCC folks plan on maintaining the same ABI indefinately (who knows
what that means). There were no ABI changes from 3.2.2 to 3.2.3 though,
so there will be no harm in upgrading.

I hope this answers all your questions.
