This is no problem.  You can easily run the 32-bit version of Firefox
instead of the 64-bit version.  Plugins will work just fine.  I've
done this on several version of Fedora.

I have never used VMWare, but looks like you got one positive here.

Sure am.  In fact, OpenOffice is 32-bit, so everyone using a 64-bit OS
and OpenOffice is.  Works just fine.  This is part of the point of the
AMD64 architecture.  Runs 64-bit, but runs 32-bit as well as 32-bit
processors.  The only things to watch out for are programs with 32-bit
only plugins (like firefox or anything using Windows codecs) and
things that have to go in the kernel (like ndiswrapper for a while
(though it works now in 64-bit with a 64-bit Windows driver)).

Definitely go with the 64-bit.  I recently rendered a 3D animation
under Blender comparing the speed between Windows (32-bit) and Fedora
(64-bit) and it rendered *more that twice as fast* (180 frames, 64-bit
12:35, 32-bit 28:25 (min:sec)) in the 64-bit version.  I need to try
32-bit Blender on 64-bit OS and on 32-bit Linux to really have a good
comparison of the speed difference, but I think this shows that 64-bit
can be much faster.  If you have problems that you cannot get around,
you could always install both in a dual-boot configuration.
