It currently has 12GB of RAM so I'd like to make sure I have the 64 bit version of R so as to take advantage of the extra memory. Since it's a power CPU server that means I'll have to compile R from source.

Just running the 64bit version of the OS usually suffices (at least on
Linux variants). Easiest check on a running R is
which gives 8 on 64-bit builds.
