Probably the easiest way is to first make sure you have a .rpmmacros
file (in at least root's home directory, also any users that you
routinely use to solve dep issues) ... in that file, put this line:
%_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch}
That will make all rpm queries show you the $ARCH of the RPMS ...
as for your specific questions...
1. I think is already answered
2. Firefox/Evolution i386 - perhaps not needed. Some things are
difficult to do with Firefox-x86_64...specifically getting java applets
to run. IcedTea is getting close but is still imperfect. I have heard
reports of getting Blackdown's 64 bit version of Java and their plugin
to work with Firefox but I don't recall seeing anyone suggest that they
can get Sun's jre/jdk 1.6.003 plugin to work in 64 bit Firefox.
nspluginviewer is your friend - be sure to run it anytime you add 32 bit
plugins (flash/acroread)
3. Don't know...I presume the standard x86_64
4. I don't know that 64 bit is all that much faster. I have been forced
to use it by some of the lower end Dell Optiplex systems that just don't
run well on i386. You definitely benefit if you have over 3 Gb of RAM.
For the most part, it shouldn't make that much of a difference.
