Couple of Qs ref UC Upgrade and VAFC Family Account

Hi,
A couple of queries rolled into one post here.
Have just booked PE flights MAN-MCO through Delta for next year. Our tickets are shown as "W" class which I believe is upgradeable to UC. Am I correct in assuming that we could (availability allowing) upgrade one-way for the difference in VA miles (i.e. return PE=70k miles, return UC=100k miles, Return difference=30k miles hence one-way upgrade =15k miles), plus the difference in taxes etc?
Second query relates to VA Flying Club membership. I am a member, but not my wife and daughter. If they were to get membership, in the future can "family" accounts be combined for redemptions, or do they have to be transferred with the associated fees?
Many thanks
