Sorry, you're right.
You should be able to access it like
gcc/xgcc -v

It's called xgcc to not confuse it with an installed one during bootstrap, 
I guess.

It's rather strange that the "powerpc-apple-darwin6.2" folder is empty. It 
should contain one or more support libraries.

It says "permission denied" because you are trying to execute the gcc 
folder itself, not a file.

No.
After "make install" everthing will be in the directory specified by 
--prefix during configure.
But, if you cannot install, in the gcc subfolder of the objdir folder there 
should be a (working ?) GCC called xgcc.
If not, bootstrap was not succesfull.
So, after installation, you can safely delete the objdir folder.

Similar.
gcc@gcc.gnu.org is used for the *development* of GCC itself, and feedback 
from succesfull bootstrp and installation is sent thre to be added to the 
"succesfull build" page.
gcc-help@gcc.gnu.org is used to ask help on *using* (and installing, of 
course) GCC.

See above.
However, I've just done a clean boostrap under Linux (w/ C, C++, Fortran 
and Ada), and the *installation* folder is slightly bigger than 200 MB...

At this point, I'd try somthing along these lines:
completely erase the objdir folder
make a new one
configure with the same options as before, plus --prefix=whatever you 
coose, with
   ../[srcdir]/configure > ../"configure output".txt 2> ../"configure 
errors".txt
bootstrap the compiler with
   make bootstrap > ../"GCC output".txt 2> ../"GCC errors".txt
try to install with
   make install > ../"installation output".txt 2> ../"installation errors".txt

If you DON'T get a working compiler in the --prefix= direcotry (under its 
bin subfolder, actually), put those 6 files in an archive (possibly .zip, 
.tgz, anything but a MacOS archive) and mail them to me, so that I can try 
to see wht went wrong.

Good luck,
