There is a variable in yum.conf called multilib_policy ...

The default in CentOS 5 is all ... the default in CentOS 6 is best.  I
personally like best better.  I only have the bare minimum i386
libraries on my machines (usually none but sometimes a few libraries on
workstations)

If you like, you can set multilib_policy to all after you install the
i386 items you want on your x86_64 install.

I can tell you that I would personally use something like mock to build
or 32-bit items in at least a clean chroot when building/compiling 32
bit things on a 64-bit machine.  But to each their own.
