You could eliminate one 13' stand if you get the combo/boom and you're in the $1500's. Your setup with the busy bee package didn't seem to include backdrop items. Personally, if you have a 430, you could start using that for a background or hair light with the Einstein and eliminate the AB400. Just some suggestions.
