Advice on redemptions

Hi,
We are planning on going east next year for our holidays for a change and were hoping virgin does keep the Hong Kong route open, but I have a few questions that I'd really appreciate some help on.
While I have 120k FC points which is enough for a straight redemption return to Hong Kong in UC, my partner only has 70k. Which is enough to upgrade E-UC one way and PE-UC return (total 65k), so i understand an upgradeable PE ticket is much more expensive than a E would I be better buying the miles needed? or using miles booster from our last flight flown (Lon-Las return) Or any other suggestions for getting the additional 20k miles (already both got amex gold, virgin white and I've got the black). Would getting the black for my OH make better sense? Or does anyone need an amex gold recommendation?
any suggestions advice would be greatly appreciated.
