The libvirt RPC protocol is arch-invariant, so you can use
a 32-bit libvirt library to talk to a 64-bit host, and
vica-verca. So you can install the 32bit library if desired,
but really 32-bit is dead technology, so its better to just 
recompile any apps for 64-bit.

You can't reliably get any of that information without having
an agent running inside the guest OS. Currently libvirt does
not concern itself with guest agent services, the focus being
primarily on host OS management. There's a small chance this
may change in the future, but its too early to say for sure.
