Some of them are used by the makefiles, some by the compiler and some by the user.

It doesn't matter whether it is 32 or 64 bit, it will do exactly the same (except for "fpc", which will call ppcx64 if it was compiled for 64 bit, and ppc386 if it was compiled for 32 bit).

3. Install everything to the same prefix. Add CROSSINSTALL=1 to the "make install" line for which you do *not* want to install the utilities (e.g., if you want the default compiler to be the i386 one, add CROSSINSTALL=1 when installing the 64 bit compiler)
