Can I use my copy of WOV with the SF Gold version on XP, or do I need SF Gold? Would it be better to just get SFII since I imagine I'll end up going to Windows 7 before too long. Also, does the game support gunners as in the Avenger or Dauntless? ( I know those will be in later mission sets.)

You can use a fresh install of WOV 122503 patched to Oct 2008 if you wish with SFG version of RSXP. Your upgrade to the Win7 version will be shipping and handling only.
