Use GPT labels.  Or UFS filesystem labels:

Even on single-disk systems, labels make it easier to deal with 
partitions.

Yes.  But unless you have a strong requirement to run XP on bare 
hardware (like for games), install VirtualBox and run it as a VM.  That 
makes it easy to transplant elsewhere when the need arises.
