I'd go with an i386 install unless you have more than 3GB of RAM, in
which case I'd go with an amd64 install (or an i386 with a 686-bigmem
kernel).
If you have other i386 machines around, it may be convenient for you to
keep the same architecture so you can share the download bandwidth of
Debian updates, and things like that.
